--- Comment #2 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:b510b83aad52adf94d52a6ae3a3b332946e947a1 commit r14-4138-gb510b83aad52adf94d52a6ae3a3b332946e947a1 Author: Patrick Palka <ppa...@redhat.com> Date: Tue Sep 19 08:29:39 2023 -0400 c++: overeager type completion in convert_to_void [PR111419] Here convert_to_void always completes the type of an indirection or id-expression, but according to [expr.context] an lvalue-to-rvalue conversion is applied to a discarded-value expression only if "the expression is a glvalue of volatile-qualified type". This patch restricts convert_to_void's type completion to match. PR c++/111419 gcc/cp/ChangeLog: * cvt.cc (convert_to_void) <case INDIRECT_REF>: Only call complete_type if the type is volatile. <case VAR_DECL>: Likewise. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/concepts-requires36.C: New test. * g++.dg/expr/discarded1.C: New test. * g++.dg/expr/discarded1a.C: New test.
