So (a) this signature is not great because it's lumping together a bunch of different crash stacks. e.g. [1] and [2] are both having the same signature and are different stacks from each other and from the one in comment 0. This should have been fixed in bug 1505954 so I left a comment there asking for clarification. And (b) the crashes with this signature all have the same buildid, and will likely have a different signature on different buildids. Bug 1502717 should fix one source of these crashes but there are still others I guess.

For now let's use bug 1507323 to track the remaining get_relative_transform crashes.
Bug 1505954 is now deployed, so we should be getting better signatures, at least for the crashes that have to do with out-of-bounds access in rust.
