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: ---

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.
