Bug ID: 107464 Summary: Expression error in qualified name lookup with lambdas in unevaluated context Product: gcc Version: 13.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: roma.sandu at gmail dot com Target Milestone: --- Created attachment 53795 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53795&action=edit Minimal bug repro I've discovered an interesting bug with unevaluated context lambdas. In the attached examples, trying to instantiate `boo` with a qualified name results in an expression error. If we instead bring the name `spooky::boo` into the `evil` namespace with a `using` statement and instantiate `boo` through an unqualified name, it works as expected. And finally, if one removes the unevaluated context lambda in `boo`'s definition, it works in all cases.
