Can't build 'text' package with llvm backend

Question

I have ghc-8.0.1 and llvm-3.7.0 both 64bit. I'm trying to install 'text' package like this:

cabal install text-1.2.2.2 --ghc-options="-fllvm -pgmlo opt -pgmlc llc -optlc-O4 -v -keep-llvm-files -keep-tmp-files"

It fails with the following message:

I installed other packages with llvm backend, so far only 'text' fails.

Answer 1

On an OS-X system using llvm 3.7 and GHC 8.0.2 I was able to (in a temp directory):

cabal sandbox init
cabal install text-1.2.2.2 --ghc-options="-fllvm -pgmlo opt -pgmlc llc -optlc-O4 -v -keep-llvm-files -keep-tmp-files"

Which yielded significant text ending with:

So in short this is a non-reproduceable (by me) platform/tooling issue. I suggest you try GHC 8.0.2 since 8.0.1 is, well, lesser. It might also be worth glancing at the windows-specific bugs on the GHC trac.
