--- Comment #2 from Volker Reichelt <reichelt at gcc dot gnu.org> ---
Thanks for pointing that out, Adam!

So here are two updated testcases. The first one contains multiple programming
errors:

=================================================================
template<typename T, float, int, typename U> void foo(T, U) {}

void bar()
{
  foo(0, 0);
}
=================================================================

The second one only contains a single error. but requires "-std=c++11":

=================================================================
template<typename T, float = 0, int = 0, typename U = int> void foo(T, U) {}

void bar()
{
  foo(0, 0);
}
=================================================================

Both crash since GCC 4.7.0.
