Comment (by bgamari):

 With GHC HEAD I get,
 {{{
 $ ghc --make hi.hs -O -main-is strangeClosureType
 [1 of 1] Compiling Main             ( hi.hs, hi.o )
 Linking hi ...
 $ ./hi
 2111752566
 hi: Out of memory
 }}}

 rwbarton, I suppose your thought was that the primop implementations
 should also do their own integer overflow checks? I'm not entirely
 convinced that is necessary.
