>Description:
	libpthread is crashing when multiple threads are working inside of a loop 
	that is thread-safe inside of my ray-tracer.  When I set libmap to use libc_r 
	instead of libpthread everything just works.  Using libpthread with just 1 thread 
	also works just fine.
>How-To-Repeat:
	Cannoy paste my example code, not open source, try making a simple 
	multithreaded program using libpthread.
>Fix:
	No idea.
