OK, I'll add the test.
When I apply this patch and compile your test, I see DependentScopeDeclRefExpr
gets converted to DeclRefExpr when the function is instantiated. This doesn't
happen without this patch, but somehow clang still manages to emit the same
code.
Also, Erik Pilkington pointed out that clang still crashes when it compiles the
following code. I'm trying to figure out why that happens.
// Template variable case:
enum class foo { a, b };
template <class T> auto a = [](foo f = foo::a) { return f; }();
auto foo1() {
return a<int>;
}
// Template struct case:
template <class T> struct func {
void bar() {
enum class foo { a, b };
[](foo f = foo::a) { return f; }();
}
};
template struct func<int>;
