Today Firefox froze completely when I was doing a walk through the Google datacenter via Google StreetView.

1. Load,-81.548671&spn=0.005945,0.012306&sll=35.900197,-81.547024&layer=c&cid=7373938251588581469&panoid=QJRzrgIKmN4uPQg7lmOGww&cbp=13,119.83,,0,3.72&gl=US&t=m&z=17&cbll=35.898621,-81.548447

2. Enter the building and take the stairs into the second floor

3. Turn right and quickly go forward so you pass the green wall

At this point Firefox freeze and I  had to force kill the application. I will attach a sample made with activity monitor which will hopefully be of help. So far I haven't been able to reproduce it.
Hmm.  This looks like a dup of bug 799282 (via bug 800393), but that claims to be fixed on Aurora...

*groan* not again :(
Marty, how hard would it be to introduce a cutoff to range analysis? We've seen a few sporadic cases of it hanging browsers, even after bug 799282 landed. If this is simple, it would be a free stability win until we get better STR.

oh, I have a patch for that lying around.  I'll post it as soon as I can find it.

fixed up the non-posted patch to be more compatible with any future changes.

We may want to not close this bug, since this is just a workaround / a measure to detect when this happens in the future, not an actual fix.
Whiteboard: [ion:p1] → [ion:p1][leave open]
Marking FIXED since range analysis has changed significantly, the workaround will only exist on branch.

Bug caused by (feature/regressing bug #): IonMonkey
User impact if declined: Possible hang on Google street maps
Testing completed (on m-c, etc.): Yes
Risk to taking this patch (and alternatives if risky): Very little, it detects when a small performance analysis pass in IonMonkey might hang and aborts the pass.

I just want to note that this was a one-time crash for me and I was never able to reproduce. So it might be hard to really verify that.
Marking this [qa-] since this was a one-time crash that was not reproducible, as per comment 15. We won't be able to reliably verify this is fixed.
