I''ve been trying to debug a Videoscape reader for the past week. It looks like it should work correctly, but GDB keeps giving exit codes instead of successes(and complains about something in libc-start). Where are the GDB exit codes listed--I''ve spent a day and a night trying to track them down, but they apparently feel I should be able to understand from just the octal code(0100, although before I removed two lines of code it was 033).

This may be a sign that either gdb is broken on yer
system or the program yer debugging was not linked
right.

The exit codes for gdb wouldn''t be reliable anyways
under this case. You might want to try upgrading
to a clean new distribution of Linux if the basic C
libs appear broken as horribly as you explained.
