A similar problem happens when template-type parameters are involved.

// -- test2.cc
template <int N>
struct A { };

template <typename Q>
void g2()
{
    const int M  ( sizeof(Q) );
    A<M> a;
}

void h()
{
    g2<int>();
}

$ g++ -c test2.cc
test2.cc: In function ‘void g2()’:
test2.cc:8:8: error: the value of ‘M’ is not usable in a constant expression
test2.cc:7:15: note: ‘M’ was not initialized with a constant expression
test2.cc:8:8: note: in template argument for type ‘int’ 
test2.cc:8:11: error: invalid type in declaration before ‘;’ token

Should I open another PR for that one?
