Comment (by bgamari):

 I have confirmed that c1c0985416a6f9766c03d361449f556905bf8e1d really is
 the first bad commit.

 I also noticed that it is possible to reproduce the crash using `forkIO`
 instead of `forkOS`, which makes it a bit easier to debug. Presumably this
 is safe since there are no native dependencies.
