--- Comment #14 from Andrew Pinski <pinskia at gcc dot gnu.org> --- I suspect this is a GC (garbage collection) issue. It might be easier to reduce it using --param ggc-min-expand=1 --param ggc-min-heapsize=1 (and then moving them both to 0 afterwards). https://gcc.gnu.org/wiki/A_guide_to_testcase_reduction?highlight=%28reduce%29
