Please include the complete backtrace with any bug report. See <https://gcc.gnu.org/bugs/> for instructions. Version: gcc-13.2.0 built from git releases/gcc-13.2.0 In constexpr.cc at line 7908, the assertion gcc_assert (cxx_dialect >= cxx23) is present. However, when I compile with the -std=c++11 option, this ICE does not occur.
