Surface Child tries to send a delete message from Plugin Instance Child::Actor Destroy()
This bug was filed from the Socorro interface and is report bp-46bd127f-056b-47f1-ae3b-1dc652160608. =============================================================
PluginInstanceChild::ClearAllSurfaces() calls PPluginSurfaceChild::Send__delete__(), but I think it fails because we're already in some kind of shutdown or error state.
I see 195 crash reports with this signature.
This should only be for the new async drawing mode which is in Flash betas but not Flash release. dvander?
Priority: -- → P2
72% of these crashes are with Flash version 184.108.40.206, which looks like the current version you can download. (Another 17% are on 220.127.116.11.)
It looks like this predates direct drawing. We're trying to send a __delete__ message over IPDL, but sending anything after an ActorDestroy will trigger a MOZ_CRASH. I think we can just set these actors to null so PluginInstanceChild doesn't try to access them again.
