Comment (by osa1):

 This is a `mmap()` failure. Not sure how to debug as I can't reproduce it
 on my Ubuntu 16.04 laptop when I run the last few commands that allocates
 the large vector and evaluates it.

 It'd be helpful if we could have a reproducer as a ghci script (i.e. a
 text file with list of GHCi commands that triggers this error).
