--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- And, just to verify it, I've compiled the testcase with r11-39 with a breakpoint on pass_expand::execute and set global_options.x_optimize = 0 there, and resulting testcase passes. So most likely things go wrong during RTL optimizations.
