You might want to try turning on symbols for a few of the key routines 
so you can determine the address space that your application is loaded 
into.  This can easily be done with pragmas:

void Foo()
{
   // ...
}

#pragma traceback on

int main()
{
   // ...
}

#pragma traceback reset

Now your crashlog will show main as one of the routines on the stack.  
From the address listed there and and address in the xMAP file, I think 
you can come up with an offset and apply that to the crashlog addresses 
to translate them into the routine names.
