My libpthread was stripped, but I had the debug symbols stored in a
separate file.  In some cases the debug symbols were being found, in
other cases they were not being found.  I was able to use 'set
debug-file-directory' to direct gdb to the debug symbols, as well as I
was able to move the symbols to a suitable location for gdb to find
them by its lonesome.

I kept thinking that I didn't have stripped libs because of the case
where gdb was working as usual. It just happened, in that case, gdb
was able to find the debug symbols.

Thanks again!
