Please edit your post and make sure your code is [code]between code tags[/code] so that it has syntax highlighting and line numbers, as well as proper indentation.

The function you posted has a return type but does not contain a return statement. You probably meant to add return *this; - it is a common mistake that I often make myself.

Use your IDE's debugger to isolate which line the crash is happening on.
