Comment (by thoughtpolice):

 The only way I can get this to *not* segfault is if I completely disable
 optimization with `{-# OPTIONS_GHC -O0 #-}` in `CodeGen.hs`. I'm going to
 see if the build completes and run the testsuite again to see what it
 says...

 (BTW, this is a typical performance build, so everything will be compiled
 with -O, at least).
