Actually, rather than figure out git bisect (warning: it opens a new branch
and after you're done you have to manually get rid of it and get back to
'master') - since there are only 4 commits in question you could simply check
out each of the 4 and see which is the first one that gives you the crash.
Thanks, by the way, for being willng to help figure this out!
