ICE-triggering source.
I get an ICE with the attached source, from version 4.8 on to the head of the
Git repository.
Output of Git's cc1plus:
Foo::Foo() Foo::Foo() Foo::Foo() Bar<T>::Bar(U) Bar<T>::Bar(U) [with U = Foo;
T = Foo] Bar<T>::Bar(U) [with U = Foo; T = Foo] Bar<T>::Bar(U) [with U = Foo; T
= Foo] void __static_initialization_and_destruction_0(int, int) void

When uncommenting the commented-out fourth attribute of Foo, the ICE goes away.
