Hello All:

I recently compiled and installed gcc 3.0 on our Alphas running
Tru64 UNIX 5.1a. I then used that version of gcc to build gdb 5.1.
The compilation of both gcc and gdb was done one an Alpha 600 5/333
(an EV5 machine).

Gdb 5.1 compiled without errors, but fails when I try to use it.
For example, I start with this tiny "hello world" program:

        #include <stdio.h>
        main(int argc,char *argv[]) {
        printf("Hello World\n");
        }

I compile it like this:

        gcc -g hello_world.c

The program runs correctly:

        % ./a.out
        Hello World

I then run gdb like this:

        gdb a.out

Here's the resulting gdb output, showing the errors:

Has anyone else seen this problem? Any solutions?
