--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Nathaniel Shead <[email protected]>: https://gcc.gnu.org/g:9813e49e95bc4bc2f0e030a7fdd0e7ef63c056fc commit r16-6596-g9813e49e95bc4bc2f0e030a7fdd0e7ef63c056fc Author: Nathaniel Shead <[email protected]> Date: Thu Jan 8 20:38:43 2026 +1100 c++/modules: Mark implicit using-directive for imported unnamed namespace as imported [PR123393] The assertion failure in the PR is due to the implicit using-directive for the anonymous namespace not being considered imported, because make_namespace_finish calls add_using_namespace without propagating 'from_import'. PR c++/123393 gcc/cp/ChangeLog: * name-lookup.cc (make_namespace_finish): Pass from_import to add_using_namespace. gcc/testsuite/ChangeLog: * g++.dg/modules/namespace-18_a.C: New test. * g++.dg/modules/namespace-18_b.C: New test.
