Description Johan Walles 2003-04-30 09:58:03 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3b) Gecko/20030210

Description of problem:
If you have gdb attached to a program and gdb is killed, it is no longer
possible to attach another instance of gdb to the running program.

I have reproduced this on RHAS on ia32 and ia64.

Version-Release number of selected component (if applicable):
5.1-1 on ia32 and 5.2-2 on ia64

How reproducible:
Always

Steps to Reproduce:
1. Start a program that runs for a long time (will attach example).
2. Attach to it with gdb.
3. killall -9 gdb
4. Attach to it with a new gdb instance.


Actual Results:  Gdb hangs trying to attach to the program.

Expected Results:  Gdb should have attached to the program.

Additional info:  Will attach example program.
