I take that back, this is invalid code still, the typename keyword is not valid outside of a template.
Reduced testcase:
template<class> struct f {};
f<int> f2[2] = {typename f<int>()};

This is a regression from 3.3.3.  We should be able to recover much better in 3.4.0 than we did in 3.3.3 
but we don't.  In fact I would have assumed that we would get a better error message before ICEing.  
Even though in the full testcase we don't get an error, we do in the reduced testcase though:
t.cc:3: error: expected nested-name-specifier
