--- Comment #3 from Aaron Watry awatry@gmail.com --- Grumble.. I was just attempting to get the bitcode since I had lost my previous dump of that... and now for some reason the GPU's not locking and I'm instead getting an LLVM diagnostic handler and a segfault due to invalid reads (according to valgrind).
I'm pretty sure I'll be able to reproduce this, but part of my software stack needs to be rebuild first.
