Which functions? I can do a more specific test if I know where to look; it's possible I just didn't test those while runnign random examples.

Hmm...
The backtrace (from ex_shader) is
Program received signal EXC_BAD_ACCESS, Could not access memory.

I apparently didn't build with debug support, I'll recompile and post the corresponding log file (will be later in the day though). If I have time I can try to backtrack to when it worked.
