Perhaps this should be an error or an assertion failure instead. Raising the value of MAX_PROGRAM_TEMPS worked around the infinite loop in my case. I also needed to increase INST_INDEX_BITS to avoid an intermitant assertion failure from mesa_src_reg_from_ir_src_reg(), though this may not be directly related.
