--- Comment #4 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
We're hitting the assert here:
/* In a template parameter list, a type-parameter can be introduced
by type-constraints alone. */
if (processing_template_parmlist && !placeholder)
{
/* In a default argument we may not be creating new parameters. */
if (parser->local_variables_forbidden_p & LOCAL_VARS_FORBIDDEN)
{
/* If this assert turns out to be false, do error() instead. */
gcc_assert (tentative);
return error_mark_node;
}
so presumably we should change it to error() as the comment says.
