You can see the patch here:

We picked this up on trunk as part of a Breakpad sync in bug 510920, but that feels like way too much to take on a branch. However, this patch is pretty small and localized, and I'd feel safe taking it on a branch. It makes crash reports a lot more useful in these circumstances.

I'll put together a 1.9.2 patch for it.

branch patch

The patch applied cleanly to branch, except for changes to some files that aren't present on branch that we don't actually use in Mozilla anyway (Breakpad added a mac framework that we're not using, and I had to patch some things there).

This is a diff against 1.9.2. I'm not sure on procedure here, since this same change already landed on trunk, and has review upstream from a Breakpad peer. Do I need review again? Just approval?

Well, better to set the flag than not. See the previous comment for an explanation.

I think we could take this on 1.9.1 as well, if it applies cleanly then it's probably fine.

branch patch

We should take this on 1.9.1. It gives us useful extra data in crash reports. It's a pretty small patch and has been on trunk and 1.9.2 without any known problems for a while.

Really too late for if it's not a blocker. We'll have to pick this up in

That's fine, just forgot to request approval and wanted it on the radar.

Pushed to 1.9.1:

You can verify this fix by installing "Crash Me Now Advanced", then using Tools -> Crash Me! -> Null pointer deref!, submitting the report, then visiting your crash report and ensuring that the "Crash Address" field is "0x0". Note that this bug is for OS X only.
