Comment (by simonmar):

 On Linux this test triggers the `stg_exit(EXIT_HEAPOVERFLOW)` here:
 https://phabricator.haskell.org/diffusion/GHC/browse/master/rts/sm/MBlock.c;c78fedde7055490ca6f6210ada797190f3c35d87$202

 It repeatedly allocates 2GB arrays and eventually runs out of the 1TB
 address space.
