Lua "C stack overflow" SIGSEGV/SIGABRT crash.
These files in combination cause a C stack overflow error to crop up in the console (intended behavior), but they also seem to cause either a SIGSEGV or a SIGABRT every time they run.
Tested on a 64-bit Linux build of what was latest master at the time of compiling. It'd be interesting to see if this happens in other operating systems or architectures...
