wrong line while debugging

[czerny]

Hallo!

Try the following two snippets!

The first one has a /* */ comment

Code: [Select]

#define UNICODE
#define _UNICODE

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>

/*
int __cdecl WinMainCRTStartup(void)
*/

int main(int argc, char **argv)
{
int i;
for (i=1;i<5;i++)
printf("%d\n",i);
return 0;
}

the second a // comment

Code: [Select]

#define UNICODE
#define _UNICODE

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>

//int __cdecl WinMainCRTStartup(void)

int main(int argc, char **argv)
{
int i;
for (i=1;i<5;i++)
printf("%d\n",i);
return 0;
}

while debugging the second example. The debugger is one line above the real position.
If I remove the line

Code: [Select]

#include <stdlib.h>


the problem is gone.

Can this be confirmed from anyone with 6.5 RC 4 32Bit? czerny

Could you post your project settings for that test program?

I haven't the time now to test it, but in the past the debugger of Pelles C had this problem - so I assume that this is another reason for this problem.
So we must wait for the next version of Pelles C and use a workaround still there.

This have two lines offset

Code: [Select]

#define UNICODE
#define _UNICODE

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

//int __cdecl WinMainCRTStartup(void)

int main(int argc, char **argv)
{
int i;
for (i=1;i<5;i++)
printf("%d\n",i);
return 0;
}

For now, one can get around this problem by adjusting the order of the includes.

Code: [Select]

#include <windows.h>
#include <string.h>
#include <stdlib.h>
#include <stdio.h>

int main(int argc, char **argv)
{
int i;
for (i=1;i<5;i++)
printf("%d\n",i);
return 0;
}

Smaller example:

Code: [Select]

#include "foo.h"
#include "foo.h"
int main(int argc, char **argv)
{
int i = 1;
int j = 2;
return i+j;
}foo.h

Code: [Select]

#ifndef _FOO_H
#define _FOO_H
#pragma once // error if this line exist
#endif

It seems, that this bug is not gone with 7.00.2 RC1.

Step into the attached project until you reach the pictured (error.gif) point.

The problem is with Optimizations which is a bug that has been reported several times.
