[webkit-dev] Random Failures

I seem to be getting random failures when running run-webkit-tests.

I'm not sure if they are related to any changes I've made or not...

I see this one most often:
running css1/conformance/forward_compatible_parsing test -> failed

which I originally attributed to using Bison 2.0...

but it doesn't always fail there.  I've seen others:
running editing/deleting/delete-3928305-fix test -> failed
running editing/deleting/delete-and-undo test -> failed
running editing/deleting/delete-3608445-fix test -> failed

each time it seems to be a crap shoot as to whether it will succeed  
or fail at some random test.  Cosmic rays?

Cryo, bdash and Altha on #webkit are seeing similar issues.

About half the time all tests succeed, half the time one of them fails.

I've tried rolling out:
neither helped.

Those are the only fixes I made today which I thought could relate to  
these crashes at all.  Again, I have determined (and bdash has  
confirmed) that neither is related.

Off to bed now.  I'm not much use to anyone at this hour.


p.s. it is remotely possible that either:
are at fault.  Neither seems likely.

One guess is that this could be an uncaught error in HashSet??  It  
seems like some sort of memory smasher since it's so random.
