GDB backtrace and register dump of the crash

While running Piglit quick on a R9 290 (see below for the full stack), I encountered a crash in src/gallium/drivers/radeon/radeon_setup_tgsi_llvm.c on line 1153 in the emit_immediate function, triggered by running spec/ARB_fragment_program/fp-long-alu. The attached file contains a full backtrace and a register dump. Let me know, if you need something else.

This might be a duplicate of bug 82477 (or at least caused by that), but since the crash happend somewhere else, I filed my own report.
