Hi All, Thanks much for your suggestions and help. Shall get back after reading through and trying some stuff mentioned in the emails. Thanks and regards, Mithun --- skip@pobox.com wrote:

Sorry, I missed this the first time round and just saw Dustin's reply. The Python distribution comes with a gdbinit file in the Misc directory. I use it frequently to display Python stack traces from within GDB. Here's the most recent copy online:
http://svn.python.org/view/python/trunk/Misc/gdbinit?view=markup
The following commands are implemented:
pystack - display the full stack trace pystackv - as above, but also display local variables pyframe - display just the current frame pyframev - as above, but also display local variables up, down - move up or down one C stack frame, but display Python frame if you move into PyEval_EvalFrame
This should all work within active sessions and sessions debugging core files (e.g., no active process).
It needs some rework. For instance, it assumes you're running within Emacs and puts out lines gud can use to display source lines. These look a little funky when debugging from a terminal window.
