Re: [RFC] mdebugread.c: Fix IRIX segfault

[Kevin Buettner <kevinb@redhat.com>]

I made some small changes to the patch based on some feedback from Joel.
(Joel recommended that issNull be used instead of 0.)  Joel also took a
look at the debug info which was problematic before.  As I understand it,
my patch should not cause any new difficulties with that code.

I've just committed the patch below.

	* mdebugread.c (parse_symbol): For stEnd, we're done counting
	when iss is issNull.
