--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Ilya Leoshkevich <i...@gcc.gnu.org>: https://gcc.gnu.org/g:ba4cfef0a45dd50e16ca7bee158bc630fa646ee7 commit r14-7012-gba4cfef0a45dd50e16ca7bee158bc630fa646ee7 Author: Ilya Leoshkevich <i...@linux.ibm.com> Date: Mon Jan 8 10:11:59 2024 +0100 asan: Do not call asan_function_start () without the current function [PR113251] Using ASAN on i686-linux with -fPIC causes an ICE, because when pc_thunks are generated, there is no current function anymore, but asan_function_start () expects one. Fix by not calling asan_function_start () without one. A narrower fix would be to temporarily disable ASAN around pc_thunk generation. However, the issue looks generic enough, and may affect less often tested configurations, so go for a broader fix.
