So this makes at least two people for who gdb dont work with threads on
i386. gdb has a way of not working after the first break for programs
when linked against pthread.

John Gordon produced a patch that worked for him on PowerPC but his
patch causing segfaults on my machine.(check archives )

Well as an alternative if you need to threads there is a program in
libpthread directoray called debuglog , it dont get compiled on install
but you can compile it manualy.  Just start the program in one console
with the -f flag then before you run your program set PTHREAD_DEBUGLOG
environment variable and you should see all sorts of traceoutput from
the libpthread library.
