Here's a recent regression (within the last 6 weeks or so):
-----------------------
struct A {
int operator() ();
};
template <int> void foo () {
A &a = *new A();
const int i = a();
}
-----------------------
deal.II/lac> c++ -c x.cc
x.cc: In function 'void foo()':
x.cc:8: error: 'a' cannot be used as a function
That's clearly bogus. Of course the error goes away once the function
is made a nontemplate.
This error triggers about a dozen times in my code...
