Memory leak std::string

[dennis_george]

UHEAP_MARK is detecting memory leak in strings. Is this a known issue and is there a work around for this?

int main(void)
{
    __UHEAP_MARK;
        {
        std::string fullpath("C:\\sys\\bin\\");
        fullpath += "any.exe"; // <--- Causes reallocation
        
        printf((char*)fullpath.c_str());
        }

#ifdef __WINSCW__
    CleanupWSD();// Cleanup all WSD related allocations
#endif
      
    __UHEAP_MARKEND;
    return 0;
}

I know that openc initializes WSD on its first invocation therefore it needs to be cleaned before __UHEAP_MARKEND. Therefore I added "CleanupWSD" call. But still I am getting the memory leak.

When I digged further with the help of foundation code I came to know that cleanup of the internal memory is not happening for strings. The cleanup code is defined under "_STLP_DO_CLEAN_NODE_ALLOC" macro which is not defined.
Is there a workaround so that I don't see this memory leak. I want to find other leaks in my program but because of this I am unable to proceed further.

Based on that, it may be a possible workaround to have this initializion outside the _UHEAP_MARK block. What happens if you put some dummy std::string before it (and test with/without CleanupWSD())?

CleanupWSD is added only after I realized there was a memeory leak. Earlier hooklogger was showing memory leak in locale used internally in string. When I added CleaupWSD that problem is resolved.

Now the memory leak is happening in the internal memory used to store the string. This memory is allocated when I use "+=" and not during the construction of the string class. As I mentioned before during the destruction of the string class this memory is not freed because "_STLP_DO_CLEAN_NODE_ALLOC" macro is not defined.

Are there any Nokia OpenC developers on this forum?

Is this a bug in Symbian OpenC? Since Symbian is no more open source is there a way to raise bug?

You can post it in the Feedback boards, the first ones you see when visiting http://discussion.forum.nokia.com - I would suggest either the Tools and SDK-s, or the platform (S60+S40) board there .
