--- Comment #1 from Patrick Palka <ppalka at gcc dot gnu.org> ---
And we ICE when the local class has a dependent base:
template<class T>
void f() {
[](auto parm) {
struct type : decltype(parm) { };
};
}
template void f<int>();

c++: local class in generic lambda [PR113544]
My earlier commit r14-278-gd60cbbfaa9a3ad was a start toward better
handling of local classes in generic lambdas, but isn't actually useful by
itself and breaks this testcase, so let's revert it for now.
PR c++/113544
gcc/cp/ChangeLog:
* pt.cc (instantiate_class_template): Don't partially instantiate.
(tsubst_stmt): Likewise.
gcc/testsuite/ChangeLog:
* g++.dg/cpp1y/lambda-generic-nested3.C: New test.
