--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I can't reproduce this, either with 6.x nor trunk, with -O0 I'm getting various error: call to ‘__compiletime_assert_149’ declared with attribute error: BUILD_BUG_ON failed: MODULES_VADDR < __START_KERNEL_map like errors, and with -O I'm just getting expected errors due to undefined symbols, but no ICE.
