The SEGV is deliberate. Only if the signal isn't caught is there any
problem. You should continue after you see this signal.

Try it without threads to begin with.

This probably means that you have sched_yield in a system header file
but you don't have it in the libraries you're linking with.
You may either comment out this:
./include/posix-threads.h-_Jv_ThreadYield (void)
./include/posix-threads.h-{
./include/posix-threads.h-#ifdef HAVE_SCHED_YIELD
./include/posix-threads.h: sched_yield ();
./include/posix-threads.h-#endif /* HAVE_SCHED_YIELD */
./include/posix-threads.h-}
or find out which library contains sched_yield and link with it.
