 Could be. I just tried to rebuild 7.6.3 with 7.6.2, and got the same
 error:


 {{{

     (GHC version 7.6.2 for powerpc_apple_darwin)

 }}}

 So it is not necessarily some problem with 7.8.x code but rather my
 initially built 7.6.2 is faulty. (Or otherwise you are right and it is
 just broken like clang.)

 I will try getting some advice from early developers of ghc for ppc, if I
 can find there contacts. Tried Christian.Maeder at dfki.de but e-mail is
 dead. He was supporting PowerPC darwin back then.
