Re: [RFA] (ping) GDB crash when using command lines due to memory corruption

There is a patch that was submitted on Oct 30th 2002 but hasn't been
reviewed because it addresses a GDB crash. It also expands break.exp
to test for this.

Can somebody have a look please?

Klee, I'll be happy to check it in for you if you lack the time.
