Version 1.15.0 of HSE was not compiled with llvm, was it? At least from what I see from the git history.
That is correct. I held back on adding HSE to [haskell-testing] for a long time due to GHC 7.8 not being able to compile it with profiling turned on. It wasn't until I had a brain fart and thought of trying with llvm that I managed to get it built. I think it was around bringing GHC 7.8 into [haskell-core] that I attempted building HSE normally again, and it worked fine. Then at the next HSE release the build problem was back and I went back to building with llvm.
