The faq (12.5) says that the default debug format doesn't store enough
information to fully debug all C++ programs. You should try building your
program with option -gstabs+ and run it under a debugger (I use the one in
RHIDE) instead.  I also suggest you read chapter 12 of the faq.

Hope this helps.
