We still give the same error, just with a caret location now:

templ.cc: In function ‘void B(V)’:
templ.cc:3:9: error: expected primary-expression before ‘int’
   a.Foo<int> ();
         ^
templ.cc:3:9: error: expected ‘;’ before ‘int’


whereas Clang is much better:

templ.cc:3:5: error: use 'template' keyword to treat 'Foo' as a dependent
template name
  a.Foo<int> ();
    ^
    template 
1 error generated.

Confirmed, here is shorter example:

{
  a.Foo<int> ();
}
