>Description:
When trying to attach gdb to a locked-up process (gaim [1] 0.59), an internal error is encountered. Here is a backtrace, taken from the corefile produced:

I'm preparing a debug build of gdb right now, so I will hopefully be able to provide you with more information soon. Please email me for any further information.
