--- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> ---
Jason, looks like some bits related to debugging are missing from the work on
return type deduction and people cannot debug uses of the new facility.

gen_type_die_with_usage gets a TEMPLATE_TYPE_PARM which doesn't know how to
handle. Is it just matter of somehow having an equivalent of is_auto and using
a DW_TAG_unspecified_type? Or we shouldn't have a TEMPLATE_TYPE_PARM at all at
this point? (I don't see what else)

... or you prefer to look a bit into this? ;)
