 `WAY=profasm` is omitted by default for this test, but the code looks like
 this:

 Test.hs:
 {{{
 import Data.List
 main = print $ length $ show (foldl' (*) 1 [1..100000] :: Integer)
 }}}

 {{{
 $ ghc Test.hs -prof -O
 $ ./Test +RTS -hc
 Segmentation fault (core dumped)
 }}}

 Reproducible with at least 7.10.3 and HEAD, also without `-O`.
