1330930 - Enhance crash data to diagnose mozilla::gmp::GMPChild::ProcessingError crashes.

Status: NEW

(Core :: Audio/Video: GMP, defect, P3)

Description

[Bob Owen (:bobowen)]

Bug 1273372 and friends have all been for a generic crash (in mozilla::gmp::GMPChild::ProcessingError) that has normally been caused by the sandbox blocking the load of the DLL. (But it could be caused by other failures as well.)

Because the blocking is just done by the OS and we crash later on, we don't get much information about what the root cause might be.

Generally we've relied on reproducing user reports and taking it from there.
We've added logging in the past to facilitate this.

We should try and enhance the crash data to help diagnose or at least categorise these crashes.

FYI looks like we have the same crash as an intermittent test failure in Treeherder now: bug 1330949

This instance is likely a regression from Bug 1318965, which was backed out after this failure was logged.

The last needinfo from me was triggered in error by recent activity on the bug. I'm clearing the needinfo since this is a very old bug and I don't know if it's still relevant.
