--- Comment #3 from David Edelsohn <dje at gcc dot gnu.org> ---
FAIL: ext/vstring/cons/moveable.cc (test for excess errors)
FAIL: ext/vstring/modifiers/assign/move_assign.cc (test for excess errors)

These failures appeared with Martin Sebor's fixes to -Wmismatched-new-delete on
2020-12-14.

Do these testcases need the same "Suppress false positive warning" changes, at
least for AIX?
