--- Comment #9 from Paulo J. Matos <pa...@matos-sorge.com> --- I didn't manage to reproduce the bug yet. With the git sha before my commit 4bc0f16, I get the following on a profiledbootstrap on x64: insn-opinit.c: In function 'void init_all_optabs(target_optabs*)': insn-opinit.c:1234:1: error: verify_flow_info: Wrong probability of edge 1437->2606 66380 init_all_optabs (struct target_optabs *optabs) ^ insn-opinit.c:1234:1: error: verify_flow_info: Wrong probability of edge 1427->2598 66380 insn-opinit.c:1234:1: internal compiler error: verify_flow_info failed Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. Unfortunately running one of these takes a long time so it's a slow process to check it out since as far as I am aware it's not possible to use a parallel build. Do let me know if there's a fast way to build it. I will keep investigating.
