Bug ID: 80191 Summary: diagnostic placeholder "new initializer" must be marked for translation Product: gcc Version: 7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: roland.illig at gmx dot de Target Milestone: --- from cp/typeck.c: permerror (input_location, "%s expression list treated as compound expression", msg); The placeholder "msg" gets the value "new initializer" in init.c, but that string literal is not enclosed in _(...), therefore it won't be translated. That call seems to be the only place where build_x_compound_expr_from_vec is actually called, so having a placeholder might be unnecessary overhead.
