--- Comment #5 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:31cdfdef04701e10cffcec4578b2337684f0e4bc commit r13-6716-g31cdfdef04701e10cffcec4578b2337684f0e4bc Author: Patrick Palka <ppa...@redhat.com> Date: Thu Mar 16 14:47:43 2023 -0400 c++: maybe_constant_init and unevaluated operands [PR109030] This testcase in this PR (already fixed by r13-6526-ge4692319fd5fc7) demonstrates that maybe_constant_init can be called on an unevaluated operand (e.g. from massage_init_elt) so this entry point should also limit constant evaluation in that case, like maybe_constant_value does. PR c++/109030 gcc/cp/ChangeLog: * constexpr.cc (maybe_constant_init_1): For an unevaluated non-manifestly-constant operand, don't constant evaluate and instead call fold_to_constant as in maybe_constant_value. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/constexpr-inst2.C: New test.
