gdb 6.3 giving a "Child process unexpectedly missing" error

gdb 6.3 giving a "Child process unexpectedly missing" error

[Mike Chrabaszcz]

I am running Fedora Core3 and have recently updated.  And now, I can no longer gdb run on any program.  Any suggestions?

Regards,
MikeC.

Program terminated with signal ?, Unknown signal.
The program no longer exists.
You can't do that without a process to debug.

Is that a typo?  Is it really trying to run /test instead of ./test?

I can only say that I'm in the same boat, and also mystified.
The error is the same:

Linux was just updated on my machine.  "uname -a" says this:
