Hello

I've written a program called ArtRays that generates povray source files using
randomness. ArtRays generates the source file and then it execs povray (version
3.7.0) to render the image to a file and then ArtRays displays the file using
SDL.

I'm doing this on a Raspberry Pi2 with four cores and it is amazing fast.
Unfortunately ArtRays runs for a while and then povray crashes with the
following error:

povray: /usr/include/boost/thread/pthread/recursive_mutex.hpp:101: void
boost::recursive_mutex::lock(): Assertion `!pthread_mutex_lock(&m)' failed.

Anyone seen this before and maybe know of a fix?
