Description John Gibson 2005-08-08 18:02:40 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050512 Red Hat/1.7.8-1.1.3.1

Description of problem:
When I invoke ddd on a simple c file and attempt to "lookup" a simble gdb core dumps. I am attaching the core. If I envoke gdb from the command line I can "list" the simbol that I am looking for. This behavior did not happen in the version prior gdb-6.1post-1.20040607.52.  

Version-Release number of selected component (if applicable):
gdb-6.3.0.0-0.30.1, ddd-3.3.1-23, kernel-2.4.21-32.0.1.EL

How reproducible:
Always

Steps to Reproduce:
1. Compile simple c file.
2. Envoke ddd on the executable 'ddd diversion'
3. Insert the symbol that you are looking for in the text window and press the "lookup" button.  ie (get_random_short)
  

Actual Results:  Core dump.

Expected Results:  the code windo should scroll to the symbol that you are looking up like function "get_random_short".

oops sorry for the typos..  simble= symbol  simbol = symbol

While Bug 162882 is for RHEL4 and this Bug was submitted for RHEL3 it would be
otherwise WONTFIX due to RHEL3 being near its end of life. Please submit Issue
