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
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.
Created attachment 91409 [details]
A program that never finishes. Repro case.
This has been reported in GDB's bug reporting system as well. Bug id is gdb/1196.
