Description Jan Kratochvil 2007-04-04 09:46:28 EDT
Description of problem:
Currently any fork(2)ed child processes get out of GDB tracking which may be
unexpected by the GDB user.
It has been proven on Bug 234468.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. gcc -o dinner dinner.c -Wall -ggdb3
2. gdb ./dinner
3. (gdb) break knife
4. (gdb) run

Actual results:
Starting program: /root/jkratoch/redhat/dinner 
Program exited normally.

Expected results:
As one originally expects as after `set follow-fork-mode child':
Breakpoint 1, knife () at dinner.c:11
11        puts ("knife");

It would be helpful to get at least:
Starting program: /root/jkratoch/redhat/dinner
Detaching after fork from child process 11836.
Program exited normally.

Additional info:
Patch is a trivial oneliner.
Slightly different GDB output may be considered a Regression.
