Comment (by barracuda156):

 This might be the cause of the problem with above builds.
 Another example, failure of 7.4.2:

 {{{

 Now compare output of `-v` and `--version`:

 {{{

 bootstrap/ghc-bootstrap/work/ghc-7.4.2/inplace/bin/ghc-stage1 --version

 }}}

     (GHC version 7.0.1 for powerpc_apple_darwin)
     Please report this as a GHC bug:

 zsh: abort       -v
 }}}

 It seems that if `--version` is passed instead of `-v`, error may not
 occur.
