--- Comment #12 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Marek Polacek <[email protected]>: https://gcc.gnu.org/g:064b4be33abf46ce6944277969e77a8bc5a97202 commit r13-10475-g064b4be33abf46ce6944277969e77a8bc5a97202 Author: Marek Polacek <[email protected]> Date: Thu Aug 20 15:01:37 2026 -0400 c++: ICE with operator new[] in constexpr [PR118775] Here we ICE since r11-7740 because we no longer say that (long)&a (where a is a global var) is non_constant_p. So VERIFY_CONSTANT does not return and we crash on tree_to_uhwi. We should check tree_fits_uhwi_p before calling tree_to_uhwi. PR c++/118775 gcc/cp/ChangeLog: * constexpr.cc (cxx_eval_call_expression): Check tree_fits_uhwi_p. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/constexpr-new24.C: New test. * g++.dg/cpp2a/constexpr-new25.C: New test.
