For ths particualr error, can you take a look at the threads:
http://sources.redhat.com/ml/gdb-patches/2001-05/msg00178.html
http://sources.redhat.com/ml/gdb-patches/2001-05/msg00187.html A
similar problem was reported but a fix was not generated. Hopefully
the discussion there that can help pinpoint your problem.
What are the sections in your file?
