@nocchijiang - Without a repro I won't quite be able to come up with an adequate fix here.

Also note that if your downstream branch has `-fcas-friendly-debug-info` (same as Apple branch) then there will be some functional conflicts - I know when this patch was ported to Apple branch there were some work-arounds needed to have this compatible with `-fcas-friendly-debug-info`.
