[Bug c++/23797] New: ICE (on invalid)

[sylvain dot pion at sophia dot inria dot fr]

The attached preprocessed file compiled with g++ produces the ICE :

include/CGAL/_test_circles_constructions.h: In function 'void
_test_circle_construct(CK2)':
include/CGAL/_test_circles_constructions.h:294: internal compiler error:
Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

----------------

I have not found the time to simplify/shorten it, but I believe that there is
an invalid use of "typename" in the program.  Removing this typename makes
the compiler happy.

It took me a while to reduce this but finally:
struct CK {
  typedef int RT;
};
void f(void)
{
  2 / typename CK::RT(2);
}

Even shorter testcase:

================================
struct A { typedef int X; };

int i = typename A::X();
================================
