Confirmed, a regression.
BTW, this is not related to typeid, the following ICEs as well: ------------------------------ struct A { void foo(void); }; template <int> void bar() { A a; a + a.foo; } ------------------------------
This is invalid code as the non-template version errors out.
Working on a fix.
