Put a print in that code. It should never get called. Nothing can even generate
the MSB tgsi opcode without forcing ARB_gpu_shader5 to be enabled. If it's
getting called, that means that there is memory corruption going on.

In case it's not clear, my commit is not at fault. It just moves some code
around and makes the memory corruption that's going on due to mismatched
libgcc's go from unnoticed to noticed.
