--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Patrick Palka <ppa...@gcc.gnu.org>: https://gcc.gnu.org/g:a074ae297d5dbd69e03c6c30f9cb7720685fdb62 commit r12-8606-ga074ae297d5dbd69e03c6c30f9cb7720685fdb62 Author: Patrick Palka <ppa...@redhat.com> Date: Thu Jul 21 12:59:44 2022 -0400 c++: non-dependent call to consteval operator [PR105912] Here we're crashing when substituting a non-dependent call to a consteval operator, whose CALL_EXPR_OPERATOR_SYNTAX flag we try to propagate to the result, but the result isn't a CALL_EXPR since the selected function is consteval. This patch fixes this by checking the result of extract_call_expr accordingly. (Note that we can't check DECL_IMMEDIATE_FUNCTION_P here because we don't know which function was selected by overload resolution from here.) PR c++/105912 gcc/cp/ChangeLog: * call.cc (extract_call_expr): Return a NULL_TREE on failure instead of asserting. * pt.cc (tsubst_copy_and_build) <case CALL_EXPR>: Guard against NULL_TREE extract_call_expr result. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/consteval31.C: New test. (cherry picked from commit f70c18524221dcefa6cd26cee7b55503181bd912)
