Hi,
I've been trying to run a debug build on Mac OS, the normal build
works fine, but the debug version fails with an Illegal Instruction.
I've run it through gdb (output below), but I not sure how accurate
the information is. I think that it's the result of a stack overflow,
it takes around 2s to fail without any launch class specified. Has
anyone witnessed anything similar?
