Re: Internal GDB error

[Michael Veksler <VEKSLER@il.ibm.com>]

Check PR 1170:

http://sources.redhat.com/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gdb&pr=1170

Because of a bug in gcc or in /bin/as, bad debug information is generated.
Instead of terminating gracefully, GDB crashes the way it does. The PR
describes a work-around that you can implement in GCC.

Disclaimer:
I am neither familiar with gdb, gcc nor with /bin/as internals and
interfaces.
All I wanted is to debug my code in this setup....
