--- Comment #11 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Nathan Sidwell <nat...@gcc.gnu.org>: https://gcc.gnu.org/g:4acb3af3669db4ca79ffc97cd615fcea205bcccb commit r11-8150-g4acb3af3669db4ca79ffc97cd615fcea205bcccb Author: Nathan Sidwell <nat...@acm.org> Date: Tue Apr 13 05:03:19 2021 -0700 preprocessor: Fix column adjustment [PR 99446] This ICE was because when adjusting a column offset we could advance into a linemap for a different file. We only checked the next line map was not for a line further advanced in any file, forgetting that it could be for an earlier line in a different file. The testcase needed adjusting as column 512 was unrepresentable, once that was taken into consideration. PR preprocessor/99446 libcpp/ * line-map.c (line-map.c): Do not advance to linemaps for different files. gcc/testsuite/ * g++.dg/diagnostic/pr72803.C: Adjust expected column.
