Here is the code of the addArgument function
map<string, string> _arguments;
void MyEvent::addArgument(const char * substag, const char * value) { string sub = substag; string val = value; _arguments[sub] = val; }
This function works with char*, but the MyEventSaxHandler::characters() handler receives Unicode characters; how do you translate them? Can you post the code for that function too?
The map is working fine on its own with cyrillic characters.
I think the error is when specifying the size of the buffer as you mentionned. How do you get the size in bytes and not in char ?
You should know it; how do you get the buffer that the evt pointer points to?

As the stack shows, the crash is happening inside your own code (MyEvent::addArgument() at straits.h:125). Unless you post it, we cannot help you. Also, I see that you are creating a MemBufInputSource object that holds the XML document; but the document seems to be Unicode, but you are using strlen to compute its size. You should enter the size (in bytes) of the buffer, and not relying on strlen (that works only on non-Unicode buffers)
