Bug ID: 92169 Summary: crash on referring to a local class member by unqualified name from outside the enclosing function Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: richard-gccbugzilla at metafoo dot co.uk Target Milestone: --- [Probably no-one will ever write code like this outside a compiler test case, but filing just in case this affects non-contrived situations.] This code crashes every version of g++ that supports deduced return types: auto f() { static int n; struct Y { static int &g() { return n; } struct X { int &get(); }; }; return Y::X(); }; using X = decltype(f()); int &X::get() { return g(); }
