yesterday I had a look to this old PR and noticed that we are almost
doing already the right thing for the original testcase: we are for
classes, but we ICE (something recent) for enums. The latter issue
seems
easy to fix: handle specially enums at the beginning of
supplement_binding_1 only when the comment says, that is in templates
(otherwise we hit an assert in dependent_type_p).
Which assert? The underlying type ought to be set by the time we see
a using, and it shouldn't be a TEMPLATE_TYPE_PARM.
Here:
if (!processing_template_decl)
{
/* If we are not processing a template, then nobody should be
providing us with a dependent type. */
gcc_assert (type);
gcc_assert (TREE_CODE (type) != TEMPLATE_TYPE_PARM || is_auto
(type));
return false;
}
type is NULL_TREE.
