Here is a C++14 testcase too:
template
auto f(T a) -> decltype(a+1) { return a+1; }
template
auto f(T a) {return a;}
struct Incomplete *p;
auto b = f(p);

I think the right patch is to check to see if the pointed to type is complete
in pointer_int_sum before calling size_in_bytes_loc. But there is no function
call that is common between the C and C++ front-end
