--- Comment #2 from Nathaniel Shead <nshead at gcc dot gnu.org> ---
Confirmed. It looks like the macro expansion locations have all been folded
into the same place, and the check for
location_t pragloc = p->location;
if (!linemap_location_before_p (line_table, pragloc, loc))
continue;
in option_classifier::update_effective_level_from_pragmas passes for both the
pop and the actual pragma, so we think that we've already popped the diagnostic
during instantiation.
Interestingly the way the pragma location gets rendered in the module is 'M:',
i.e. the abstract location for the module itself. I don't think this is
especially helpful in any case.
