--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Patrick Palka <ppa...@gcc.gnu.org>: https://gcc.gnu.org/g:1e6c0e69af8da436e1d1d2d23d8c38410d78ecf2 commit r12-8214-g1e6c0e69af8da436e1d1d2d23d8c38410d78ecf2 Author: Patrick Palka <ppa...@redhat.com> Date: Thu Apr 21 08:34:59 2022 -0400 libstdc++: Work around modules ICE in <charconv> [PR105297] This makes the initializer for __table in __from_chars_alnum_to_val dependent in an artificial way, which works around the reported modules testsuite ICE by preventing the compiler from evaluating the initializer parse time. Compared to the alternative workaround of using a non-local class type for __table, this workaround has the advantage of slightly speeding up compilation of <charconv>, since now the table won't get built (via constexpr evaluation) until the integer std::from_chars overload is instantiated.
