 I have a mac application, and every time I try to attach to it I get the
following output :
http://pastebin.com/f32400775

I tried debugging the debugger and the crash has the following stack trace
(seen from the external gdb) :
http://pastebin.com/f6a1d9b68

When breaking at the crashing function bundle_basename() just before the
crash, the argument passed seemed to be correct (the file name of my
executable).

It will be a bit hard for me to supply the executable itself since it is
part of a large application with many dependencies, but I'm trying to
reproduce with a test case.

I'm using gdb 6.3.50-20050815 (Apple version gdb-1346) on snow leopard
version 10.6.1.

regards,
Yoni.
