Does anybody know of a good GDB (or other Linux debugger) tutorial for debugging multi-threaded C code? I'm looking for one that includes simple examples.

GDB provides these facilities for debugging multi-thread programs: automatic notification of new threads. ' thread thread-id ', a command to switch among threads. ' info threads ', a command to inquire about existing threads.
Use the "info threads" command to see the IDs of currently known threads. The GDB thread debugging facility allows you to observe all threads while your program runs--but whenever GDB takes control, one thread in particular is always the focus of debugging. This thread is called the current thread.
Parallel processing using many threads can greatly improve program performance, but it may also make debugging more difficult because you're tracking many threads. Multithreading can introduce new types of potential bugs.
