That stack makes absolutely no sense.  Those functions don't call each other.  Do we not have working crash report stack-walking for those builds?

We do, but that's not to say that it might not be going off the rails in this case. That whole stack is pretty nonsensical, it's possible it's just stack corruption or something.

In that case, is there any way we could progress on this?  (See bug 636674 for a similar crash stack.)

For right now, you should ignore all linux Fennec 4.0b5pre stacks, as they're almost guaranteed to be worthless because of bug 637243.

Does that mean that we should resolve these bugs as INVALID?

Yep.

We're going to try to reprocess the b5 crash reports to get reasonable data, see bug 637680. We can reopen if these bugs are still topcrashers and we get useful stacks.
