native code generator: GHC crash at GHC.Prim SIMD vector
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.
