-----------------------+----------------------------------------------------
 The `floor` function crashes with a segmentation fault in GHCi with a
 negative, non-integer-valued, Double argument.  It does not crash for any
 of the positive arguments or negative integer arguments I tried.  It does
 not crash with a `Float`.  It does not crash in compiled code.

 To reproduce, run `floor (-0.5)` in GHCi.
