Re: gdb 5.1.1 runtime error (on HPUX11.0)

[Andrew Cagney <ac131313 at cygnus dot com>]

Have a look at:
http://sources.redhat.com/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gdb&pr=366
to see if that works around the problem.

It it does, can you add the below information to that bug report.  It is 
definitly useful.
