malloc and 64 bit ?

<< < (2/3) > >>

MrBcx:
This works for me, 32-bit and 64-bit, Windows 10 Pro:


--- Code: ---#include <stdio.h>     
#include <stdlib.h>     
#include <string.h>   

int main(void)
{
char *x = (char*)malloc(128);
memset(x,0,128);
return 0;
}

--- End code ---

It is very strange. Because I have a problem. Okay, sorry, this is probably a local error.
I use Windows 10, no antivirus.

If you run my exe file from attach, it works?

John Z:
Hi,

Yes as far as I can tell the original 1.exe from your zip runs just fine, no error report.
Attached is 1_me.exe from my compile. You can try it.
Attached is also a comparison of file size, mine is exactly  1K (1024) bytes larger.

Your exe works fine
my - crashes with error
ok, thanks, maybe I need to re-install PellesC Ide

John Z:
Definitely something strange because your exe does not show any error on my system. maybe something corrupted on your system but might not necessarily be Pelles C.  Still worth a try to re-install to get 'fresh' .lib files.

I'm on Windows 11 home edition 21H2 build 22000.1219 btw.  I have windows 7 and windows 10  as well and I'm going to try your exe there too.

P.S. "No antivirus", but you are running Microsoft Defender and firewall I hope....
