The simplest way to match crashes might be literally matching the signature compared to previous crashes. I am not entirely sure if that's good enough or not.

Comment on attachment 8750740 [details] [treeherder] mozilla:crash_matcher > mozilla:master wlach: I know you haven't reviewed much in this part of the code before, but I thought it might make some sense to spread the load and get more people at least passingly familiar with the way this works. But if you are overloaded already or want me to redirect the review to emorley or camd, please just say.
