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.

Thank you for the information...I will rebuild gcc and give it a try

Is there a bug report open against gcc for this issue?

Re: Internal GDB error

[Michael Veksler]

No, there was no PR filed to gcc. I was not sure if it was /bin/as or a gcc
bug. Instead of opening a PR, I contacted people that can eventually
figure out who's fault it is, and I nag them every other month (I guess
time is up to nag them again). It seems more productive to me.

Anyway, it seems that GDB is a better place to keep this PR for
the moment, because it is more natural to look up the PR there.
So if anyone wants to find out what is the cause behind this
"Internal GDB error" she will find it in GDB's database.

Re: Internal GDB error

[Blazquez Fernandez, Miguel Angel]

Hi,

I am having the same problem.

I am able to reproduce the problem using the example in PR-1170

My environment is:

AIX 4.3.3 running on a AIX powerpc box.

G++ compiler 3.3.1

I have just tried using gdb 5.3, 6.0 and 6.1 and the problem still appears.

I would like to try the work-around for the gcc compiler but I am not sure
about the changes I have to add to the file gcc/dbxout.c

Had anyone wrote those changes??? So, I can cut and paste in order to
rebuild gcc 3.3.1

Thank you in advance.

MAB

Internal GDB error

[David Frager]

I am having problems running gdb in an AIX 4.3.3 environment.  I can set 
tracepoints, however, if I attempt to invoke any additional actions (i.e., step, 
next, etc.), I receive the internal gdb error below:

Any recommendations to help determine if this is a gdb bug or local environment 
issue would be appreciated.
