https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112732 --- Comment #6 from GCC Commits --- The releases/gcc-12 branch has been updated by Richard Biener : https://gcc.gnu.org/g:b46486ef0316240eb3c173bda062b52333507e03 commit r12-10492-gb46486ef0316240eb3c173bda062b52333507e03 Author: Richard Biener Date: Tue Nov 28 12:36:21 2023 +0100 middle-end/112732 - stray TYPE_ALIAS_SET in type variant The following fixes a stray TYPE_ALIAS_SET in a type variant built by build_opaque_vector_type which is diagnosed by type checking enabled with -flto. PR middle-end/112732 * tree.cc (build_opaque_vector_type): Reset TYPE_ALIAS_SET of the newly built type. (cherry picked from commit f26d68d5d128c86faaceeb81b1e8f22254ad53df)
