Hi there,
I'm trying to switch to VS 2005, there are some problems with porting =
existing code. I found something interesting in the project environment =
with this code:

#include <stdio.h>
#include <stdlib.h>
void abcd(char *dummy,int si,int value)
{
     int x;
     x = si;
// VC++ 6.0 shows, si = 0, value = 5
// Visual Studio 2005 shows , si = 1 (in project)
// command line "cl <file> shows si=0
// in ide project, si=1, value=0
     printf("si = %i value = %i",si,value);
}

void main(void)
{
     int si;
     si = 0;
     short int iblock[2] = {0,1};
     abcd("do something",si,iblock[si++]);
}
-------------

I don't think it's a optimization issue, since the IDE debug is turn off =
(disable) optimization. In Visual C++, I gotten the value of the index =
is (si=0) inside the body of the subroutine. In Visual Studio 2005, =
the value (si=1) inside the body.

Does anyone know which compiler feature this is so I can turn it off?

Thanks,
Robert
