--- Comment #8 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:bb2e908638758097e261bca1a4825d171a18af9c commit r11-8583-gbb2e908638758097e261bca1a4825d171a18af9c Author: Jason Merrill <ja...@redhat.com> Date: Mon Jun 14 17:37:43 2021 -0400 libcpp: location comparison within macro [PR100796] The patch for 96391 changed linemap_compare_locations to give up on comparing locations from macro expansions if we don't have column information. But in this testcase, the BOILERPLATE macro is multiple lines long, so we do want to compare locations within the macro. So this patch moves the LINE_MAP_MAX_LOCATION_WITH_COLS check inside the block, to use it for failing gracefully. PR c++/100796 PR preprocessor/96391 libcpp/ChangeLog: * line-map.c (linemap_compare_locations): Only use comparison with LINE_MAP_MAX_LOCATION_WITH_COLS to avoid abort. gcc/testsuite/ChangeLog: * g++.dg/plugin/location-overflow-test-pr100796.c: New test. * g++.dg/plugin/plugin.exp: Run it.
