--- Comment #10 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:7c365bb1462a7a9dadf9b8f8668a0c832b18056c commit r10-9844-g7c365bb1462a7a9dadf9b8f8668a0c832b18056c Author: Jason Merrill <ja...@redhat.com> Date: Sun Apr 4 01:01:56 2021 -0400 c++: constexpr if and nested generic lambda [PR99201] When building up *_EXTRA_ARGS for a constexpr if or pack expansion, we need to walk into the body of a lambda to find all the local_specializations that we need to remember, like we do in find_parameter_packs_r. gcc/cp/ChangeLog: PR c++/99201 * pt.c (class el_data): Add visited field. (extract_local_specs): Pass it to cp_walk_tree. (extract_locals_r): Walk into the body of a lambda. gcc/testsuite/ChangeLog: PR c++/99201 * g++.dg/cpp1z/constexpr-if-lambda4.C: New test.
