 When compiling LongList.hs with
 {{{
 ghc --make LongList.hs
 }}}
 then running the output gives a segfault:
 {{{
 $ ./LongList
 8595
 Segmentation fault
 }}}
 It also segfaults with ghc 6.12.1 (without printing 8595) and with ghc
 6.12.3.

 On ghc 6.12.3 running on Mac OS 10.5, no segfault is seen. (I haven't
 tried much longer input, since it already eats up approx. 1.2 GB of RAM.)
