Comment (by thomie):

 The example from the description, as well as the simpler testcase from
 comment:1, both compile fine with ghc 7.8.1 and higher:

 {{{
 $ ghc-7.8.1 -dcore-lint -package primitive --make Main.hs
 }}}

 (without `-package primitive` I'm getting "undefined reference to
 `hsprimitive_memset_Word`" errors)

 A regression test should probably be added.
