kernel 2.6.9-1.724_FC3 and gdb

When attempting to debug any program while using the newest kernel
(2.6.9-1.724) under FC3, I invariably get the following error
immediately upon executing the program:
    warning: Child process unexpectedly missing: No child processes
    Program terminated with signal ?, Unknown signal.
    The program no longer exists.

I'm no kernel hacker and have no idea where the problem might lie,
or what package needs to be fixed. But I've tested this problem with
the same result on two boxes with very different hardware configurations.


Below is a transcript of replicating this problem, just in case there's
some detail you can spot that I missed.

You can't do that without a process to debug.
