Problems with gdb after 5.1 upgrade (Tru64)

I am the admin of a server that C programming classes are taught on at a
university. About 2 weeks ago we did the Tru64 5.0 -> 5.0a -> 5.1 upgrade
and we have been having problems with the system ever since. I have
gotten most of the resolved but I cant seem to get gdb to work anymore.
Gdb segfaults any time I run a program through it. This happens with both
gdb 5.0 and 4.18 and using gcc 2.95.2 and 2.8.1. I have contacted Comapq
about it but of cource they dont support GNU software. Any help would be
much appreciated. Here is an example with a simple hello world program.
The hello.c program
--------
#include <stdio.h>
int main(void)
{
printf("\nHello world!\n\n");
}
--------
intermix.engr.arizona.edu:/home3/t/trevore/projects/tmp> gcc -g hello.c
intermix.engr.arizona.edu:/home3/t/trevore/projects/tmp> ./a.out
Hello world!
intermix.engr.arizona.edu:/home3/t/trevore/projects/tmp> gdb a.out
