Hi,in this error recovery issue get_underlying_template crashes when TYPE_TEMPLATE_INFO_MAYBE_ALIAS is applied to a null orig_type. Simply checking for that condition appears to solve the issue in a straightforward way. Tested x86_64-linux.
Wouldn't it be better if a scrogged alias got error_mark_node as the underlying type? (I have no idea whether that's an easy thing to accomplish)
