--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:7b79fa930917da735f02b4f6911dfbb0a91f9714 commit r13-4369-g7b79fa930917da735f02b4f6911dfbb0a91f9714 Author: Jonathan Wakely <jwak...@redhat.com> Date: Mon Nov 28 10:52:23 2022 +0000 libstdc++: Fix _Hash_bytes for I16LP32 targets [PR107885] For H8/300 size_t is 32 bits wide, but (unsigned char)buf[2] << 16 promotes to int which is only 16 bits wide. The shift is then undefined. This fixes it by converting to size_t before shifting. libstdc++-v3/ChangeLog: PR libstdc++/107885 * libsupc++/hash_bytes.cc (_Hash_bytes): Convert to size_t instead of implicit integer promotion to 16 bits.
