--- Comment #15 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:b14ae44ec26f932d019c5eb54c2867bd905c587f commit r13-9610-gb14ae44ec26f932d019c5eb54c2867bd905c587f Author: Jason Merrill <ja...@redhat.com> Date: Tue Apr 15 11:23:57 2025 -0400 c++: constexpr, trivial, and non-alias target [PR111075] On Darwin and other targets with !can_alias_cdtor, we instead go to maybe_thunk_ctor, which builds a thunk function that calls the general constructor. And then cp_fold tries to constant-evaluate that call, and we ICE because we don't expect to ever be asked to constant-evaluate a call to a trivial function. No new test because this fixes g++.dg/torture/tail-padding1.C on affected targets. PR c++/111075 gcc/cp/ChangeLog: * constexpr.cc (cxx_eval_call_expression): Allow trivial call from a thunk. (cherry picked from commit 628aecb050bbbc4bb0bd4468c474623e20d64e21)
