dholbert: Does this look like frame poisoning to you?

Flags: needinfo?(dholbert)

Yup, this is mitigated by frame poisoning. Looking in the gdb prompt for the pernosco trace, the frame in question (the one we're calling GetContent on) has all of its pointer member-vars set to 0x7ffffffff0dea7ff; and putting a watchpoint on one of those members and reverse-continuing, we get back to a mozWritePoison call.

So: we're crashing because we're dereferencing the frame poisoning address (on the nsIFrame::mContent member-var in this case). Should be non-exploitable.

Thanks for verifying :)

(Note: the crash signature here, nsINode::GetBoolFlag from bp-472b6ed9-a27a-4234-ae9b-0c4890230726 , is super generic and includes lots of unrelated crashes as well.)

:dshin, could you have a look please?

Martin, maybe you have cycles to look at this style containment issue?

Apologies for the delay. I started debugging this, but haven't been able to make heads or tails of it yet. I figured that there must be a null pointer involved somewhere, but haven't found anything. Perhaps a stale pointer is hanging around somewhere, but I need to do a bit more debugging.

Martin, wondering if you had any updates on your investigation?

Instead of recalculating quotes and counter before destroying contain
style scopes, calculate them after. This prevents stale frame pointers
from sticking around during counter and quote recalculation.
