Make sure you're not violating the One Definition Rule[^]. I suspect this as you said you're using STLPort. My guess is that you may not be using it contently across translations units (ie. using the default STL in some file or lib and using STLPort in another file or lib).

Possibly. At least I have a starting point with which to start looking into this now. Thanks!

Yes, In my case this was true, but not sure about yours!
I will explain mine...
First bit of a background. I am porting a project in VC6 to VC8.
So I had two projects Project1 and Project2. So my first project is a lib project. Project2 statically links to Project1. So whenever I used std::map in my Project1 class Project2 crashed. "this" was getting corrupted, I just couldn't understand what was wrong.
So my sixth sense came into play and I checked the project settings, and there it was, Project1 didn't have "_SECURE_SCL=0" defined and Project2 had this set, so obviously as we know that _SECURE_SCL does add some piece of code.
So immediately I made my project settings of all projects consistent and all crashes disappeared. 
Don't know if this is the case with you. But I am sure there is something in your project settings that's causing this problem. Most probably _SECURE_SCL related stuff.

This is a nasty problem that can be hard to diagnose. Technically it's a violation of the One Definition Rule[^].

Yeah it does sound like it has something to do with the project settings eh? I mentioned (in a separate response in this same thread) that STLPort is being used in this project; it could well be that the settings used for building the STLPort library is different (as in the case you described). Now I just need to track down the project settings for the version of STLPort we are using...worth a look anyhow.
cheers!

code:
CString myfunc()
{
return CString(_T("a string"));
}
CString myfunc2()
{
return CString(_T("a string2"));
}
int _tmain(void)
{
CString tempStr(_T("hello"));
tempStr.Empty();
tempStr= myfunc();
tempStr.Empty();
tempStr = myfunc2();

you could have step into the MFC source code and clear you mind.

when ever you assign new value to CString object, it will refresh it internal data member with new values!

ThatsAlok when ever you assign new value to CString object, it will refresh it internal data member with new values!
Does "assign new value" also count for a CString::Format () call?
So:
CString csNotEmpty = "hee hee";
csNotEmpty.Format ("another value");
Can I be sure that csNotEmpty ends up with the value "another value", or do I need to make the
(disabled) Empty () call in between?
Thanks in advance\0

this will work!

Hello everyone,
I never looked deep into the _p and dlldata file before, because they are automatically generated by MIDL compiler.
Today I opened them for study (I create them with ATL wizard), I can find and open them, but I do not understand what are the differences between _p file and dlldata file -- what are different function they are focused on?
For example, suppose I have an ATL coclass named TestATL1, then _p file I mean TestATL1_p.c and dlldata file I mean dlldata.c,
thanks in advance,
George

Hello everyone,
When making outgoing calls to other apartment in STA, the owner thread of
STA is not blocked and continue to do message pump, it is the RPC thread
(which is responsible for sending marshalled result to destination apartment)
is blocked? Is my understanding correct?
thanks in advance,
George

I just downloaded a Source from 'http://www.codeproject.com/KB/files/cfilemanip.aspx[^]'
Downloaded the zip to the desktop, with the Idea of expanding into an Appropriate Folder.
My Problem is, that the .ZIP file refuses to open, and Expand.
I get an Explorer window to Browse, but it has no menu items to expand it to a Folder.
Cannot find WinZip either to forcefully open this!

The function is like this :
int __cdecl _vsnprintf(char *Dest, size_t Count, const char *Format, va_list Args)
{
int v4; // edi@1
char *v6; // esi@1
char v7; // sf@2
FILE v8; // [sp+8h] [bp-20h]@1
v6 = Dest;
v8._cnt = Count;
v8._flag = 66;
v8._base = Dest;
v8._ptr = Dest;
v4 = sub_10078E3D(&v8, Format, Args);
if ( v6 )
{
v7 = v8._cnt-- < 1;
if ( v7 )
_flsbuf(0, &v8);
else
*v8._ptr = 0;
}
return v4;
}
I want to hook it like this i change the return address to mynes because i dont wanna change any bytes thnx for the helper

UNICODE_STRING str;
WCHAR_T WBuf[2];
WBuf[0] =L"1";
WBuf[1] =L"\0";
RtlInitUnicodeString(&str ,WBuf );
Actually when i am debugging the control comes here and then it is throwing an exception.
So i think the problem is here.

How is this compiling? Try:
WBuf[0] = L'1';
WBuf[1] = L'\0';
