--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-15 branch has been updated by Jakub Jelinek <[email protected]>: https://gcc.gnu.org/g:1788588589a534dd9b732f1ddec10aefd5d689db commit r15-10577-g1788588589a534dd9b732f1ddec10aefd5d689db Author: Jakub Jelinek <[email protected]> Date: Thu Nov 20 08:19:32 2025 +0100 c++: Fix error recovery ICE in tsubst_baselink [PR120876] The following testcase ICEs since r12-6080. The problem is that lookup_fnfields can return NULL_TREE on failure, but the maybe_incomplete handling was added before the if (!baselink) handling and assumes that baselink is non-NULL (and BASELINK). The following patch reorders the if (maybe_incomplete) handling with if (!baselink). 2025-11-20 Jakub Jelinek <[email protected]> PR c++/120876 * pt.cc (tsubst_baselink): Move maybe_incomplete handling after !baselink handling. * g++.dg/parse/crash81.C: New test. (cherry picked from commit 6bace0ed49aea613ccd6c4f3c21a9ef0473fe62b)
