Hi,
I'm developing a GUI program using ruby-gnome2. It's core dumping on exit.
How can I figure out what's going wrong? I tried using ddd on the
core dump and ruby interpreter, but didn't get very far.

You can inspect coredumps with gdb together with the application that dumped that core (ruby executable in your case, I presume). The most straightforward information you can get is the execution stack that led to the crash, if you are lucky 
(memory may be corrupted beyond recognition).
gdb -c <your core file> /usr/local/bin/ruby
When you get a gdb prompt (normally, "(gdb) "), issue command "backtrace" or "bt". Your executable must not be stripped so that you get symbolic names, not just addresses.
Gennady.
