--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:11f07ef37786d10517121fc6226681cd1aa2aea2 commit r11-6252-g11f07ef37786d10517121fc6226681cd1aa2aea2 Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Dec 18 10:07:28 2020 +0100 c++: Fix PCH ICE with __builtin_source_location [PR98343] Seems the ggc_remove ppc_nx 3 operand member relies on the hash tables to contain pointers in the first element, which is not the case for source_location_table* hash table, which has location_t and unsigned as first two members and pointer somewhere else. I've tried to change: static void pch_nx (T &p, gt_pointer_operator op, void *cookie) { - op (&p, cookie); + extern void gt_pch_nx (T *, gt_pointer_operator, void *); + gt_pch_nx (&p, op, cookie); } in hash-traits.h, but that failed miserably. So, this patch instead overrides the two pch_nx overloads (only the second one is needed, the former one is identical to the ggc_remove one) but I need to override both. 2020-12-18 Jakub Jelinek <ja...@redhat.com> PR c++/98343 * cp-gimplify.c (source_location_table_entry_hash::pch_nx): Override static member functions from ggc_remove. * g++.dg/pch/pr98343.C: New test. * g++.dg/pch/pr98343.Hs: New file.
