 When compiling attached source file, GHC panics. The following is the
 error message.

 {{{
 $ ghc -Wall Vec3.hs
 [1 of 1] Compiling Data.Vector.Vec3 ( Vec3.hs, Vec3.o )
 ghc: panic! (the 'impossible' happened)
   (GHC version 7.10.1 for x86_64-unknown-linux):
         Size.intSize W256

 Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
 }}}

 Currently native code generator does not support SIMD operations, and my
 computer does not support AVX instructions. Therefore ghc cannot compile
 the source at any case. So I think this bug is not so important.

 My system environment.
