Error in str_misaligned in application in Windows 7

[martho]

Hello!

I have developed a big application on Windows XP. Now I changed my OS to Windows 7 with a new computer.

I just copied the whole project and the settings of my Visual Studio 2005, and the compiling went well. But starting the application, I get an error


Unhandled exception at 0x5e8bb10c (msvcr80d.dll) in MyApp.exe: 0xC0000005: Access violation reading location 0x000000fe

File strlen.asm:

str_misaligned:
        ; simple byte loop until string is aligned
        mov     al,byte ptr [ecx] <- Error
        add     ecx,1
        test    al,al
        je      short byte_3
        test    ecx,3
        jne     short str_misaligned

while just concate 2 strings:

CString a = table+"."+fields[nField].name;


Uh The same code works fine in Windows XP. Any idea what I could do? I set WINVER=0x0501 in the compiling-settings (because the target-computers are mostly XP) and started Visual Studio as administrator.
