[Bug c++/20476] New: g++ crashes with a contrived template mistake.

["olsonse at umich dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

g++ gives an "internal compiler error: Segmentation fault"
    message where it should give an error about illegal code.  I've included
    code to cause the problem.  This code shows a mistake in the
    initialization of a template member.  The template was used incorrectly.

The simple problem code is:

/* The example code that causes the failure: */
template <int ndim_ = 0>
class bob  {
    const int ndim;
};

/* note that the mistake below causes the g++ crash:
 * bob<ndim> below should be bob<ndim_>
 */
template <int ndim_>
const int bob<ndim>::ndim = ndim_;

int main() {
    bob<> a;
    return 0;
}
