Hi CandCPlusPlus

The downloads are from Pelles Site not Github.  Instructions for self modification are here too.

You can use the pocc.exe patched by me or patch it by yourself. For version 12.0.1.0, only two bytes need to be modified.

First, at file offset 0x20ae64, change 0x20 to 0x28.
Second, at file offset 0x20ae8c, change 0x20 to 0x28.

Download a HEX editor - I use Hex Editor
https://mh-nexus.de/en/

then modify the two bytes.  Pelles Hex Editor might work too.
Create a copy to trial first - of course.

Instructions for poasm modifications are here too, from Master Sunshine:
Code: [Select]
For the poasm.exe v12.0.1.0, at file offset 0x4d3f4 and 0x4d41c, change 0x20 to 0x28.
Both of these are on page 3-4 of this thread...

Thanks. I don't know how I didn't see that before.

Excuse me, I don't have the source code.

You can patch it yourself.

We need programs to test, where bug exists

Perhaps checking a crt64.lib for function name.
_assert.obj ?
__crt_assert:
Code: [Select]
  [0000000000000148] E900000000                   jmp               exit

You can patch it yourself.

I did patch pocc and poide as your instructions were concise and clear.  I'm afraid these other ones (crt64,crtmt64,pocrt64) are not so clear that I can do it.  Showing binary file comparisons in this manner they are hard (at least for me) to spot the differences, I have no confidence that I could successfully patch the files using those.  A patch mistake would be far worse than the issue I fear.

We all appreciate your efforts to patch these to improve the outcomes. Thank you very much.

Hi Sunshine,

Oh the patch is working I'm sure and in any case I'm on WIN 23H2 which does not show the issue.
I was just trying the patch to see if it affected a 64 bit build that causes the aforementioned error.

Most 64 bit program compile nicely, but a few run into the Access violation error.  In some cases rearranging the code can remove the access violation but it is hit and miss.  The 32 bit build of the same code never has an issue.

Hi John,

According to my recent research, pocc has a special optimization for functions such as exit, _Exit, and abort. It uses the JMP instruction to replace the CALL instruction, but does not align the function stack frame. This problem affects the toolchain and runtime library. I patched several tools that did not work properly and patched all the places that seemed to have problems in the runtime library. Of course, only the 64-bit version needs to be patched. Especially, I patched pocc, let it emit some instructions to align the stack pointer before jump to functions like exit, _Exit and abort. So the user code can call these functions without an access violation. You may find my latest patched version on the GitHub. https://github.com/fengyoulin/pellesc

After all, I don't have the source code. I can only make small patches based on these binaries. This may not completely solve the problem, or may introduce new problems. I'm doing all this just in the hope that the tool will be usable until Pelle releases his next version.

Good luck to Pelle. Good luck to us.

https://github.com/fengyoulin/pellesc/blob/main/patcher12/main.c

This is the patcher for several tools and libs that are obviously problematic, you can build it use your PellesC. Some other tools also contain problematic code, but may not necessarily need to be patched. The problem is caused by the stack pointer not being aligned. In some tools, the problem code may not be executed, or two adjacent misaligned function stack frames in the call chain may cause the stack pointer to be realigned. How magical!

On my computer, I patched all the tools that contained the problematic code, I never encountered *** Error code: -1073741819 *** in the past few days.

Hi sunshine,

Thanks, could you provide the list of the patched Pelles tools?

I'm very happy that SunShine registered on the forum. Without him, no one would have realized that for 12 versions the Pelle Orinius tools were buggy. I use the assembler and debugger every day and I don't see where the problems are. I drew a circle with all the vertices of an octogon, I know I don't have very good eyesight, but what I drew is not a square or a diamond.
I don't understand what you're doing SunShine, it's good of you to want to make sure that the tools work correctly, even if there is an old fart who is complaining, you should ignore him.

Thank you very much - this is extremely helpful!  Excellent help for us not so inclined to assembly and patching thusly.   Once I patch all, I'll try the code I know always fails when compiling for 64bit, hopefully the patches are involved. :)

Vortex - the list from the Pelle C patch program is
"poasm.exe"
"pocc.exe"
"pocrt64.dll"
"poedit.exe"
"crt64.lib"
"crtmt64.lib"
"pocrt64.lib"

HellOfMice - Let's not forget Micro$oft also, which until WIN 24H2 was insensitive to the method and alignments used in Pelle C .....

I also want to point out that it is the Pelles Tools that have the issue, not the code the tools produce.
AFAIK nothing that was built successfully has had any issue under WIN24H2

Hi Sunshine:

Thank you for this. I compiled and ran the patch and now I can compile from Pelles C IDE. Like you, I get no more *** Error code: -1073741819 ***.

Good job !

Hi Sunshine,

Thank you for your efforts fixing the Pelles C toolchain and libs.  I overwrote my V12 files with your patched files and confirm that the
*** Error code: -1073741819 ***  that I experienced in the Pelles IDE has vanished and numerous projects compiled using your patches
compile and execute normally on Windows 11 Pro 24H2.  It seems like things generally compile faster now too but I might be imaging things.

I don't know that we'll ever hear from Pelle Orinius, let alone see a new version of Pelles C released - I hope I'm wrong.
But you could not have come along at a better time for those of us that enjoy using Pelles C. 

Thank you very much ... I look forward to reading your posts.

Hi All,

Attached patch project zip, and output results for anyone interested.
This is Master Sunshine's work, I just packaged the program using Pelles ZIP. Included is a screen capture of the output results.

Still testing, although it fixes the major problem (*** Error code: -1073741819 ***) as others report, unfortunately it does not seem to eliminate the mysterious and intermittent
Code: [Select]

Fatal error: Internal error: 'Access violation' at 0x00007ff6251c3e99. that some programs give when trying to compile as 64 bit, yet have no issue as 32 bit.

An amazing piece of work by Master Sunshine!! 

John Z

Fatal error: Internal error: 'Access violation' at 0x00007ff6251c3e99.are often an optimizer problem and possible to avoid by changing code,
like in miniz code ?


patch_poc64 is just sunshine's code compiled with Pelles C and using just OS msvcrt.dll and fprintf() to stderr changed to using printf()
Just for fun to avoid Pelles C crt64.lib

I found a solution that seems to fix this problem. By patching pocc.exe to enlarge the stack frame of one of the functions on the problematic call path by 8 bytes, then the memory addresses are aligned correctly.

You can use the pocc.exe patched by me or patch it by yourself. For version 12.0.1.0, only two bytes need to be modified.

First, at file offset 0x20ae64, change 0x20 to 0x28.
Second, at file offset 0x20ae8c, change 0x20 to 0x28.
It works but it goes slower.
Tested now again. Now go it faster than when I previously tested. Think it goes faster than original when it worked!
