3.4 is broken too, it's a regression from 3.3 actually.

Reduced testcase:

template <class T> struct ffff { static const bool value = true; };
template <class A>
struct bound_member_action
{
typedef char f[ffff<A>::value ? 1 : 2];
template <class CT>
bound_member_action(CT i, typename if_t<f>::type g) {}
};
bound_member_action<int> a(0, 1);
: Search converges between 2004-01-27-trunk (#442) and 2004-01-28-trunk (#443).
Just a note that date is when it started to seg fault.
We started to reject this (and not an ICE):
: Search converges between 2004-03-01-3.4 (#2) and 2004-03-15-3.4 (#3).
: Search converges between 2004-03-01-trunk (#446) and 2004-04-01-trunk (#447).
