Hello Mathieu, I'm using Fedora 23. The default Haskell Platform here provides ghc 7.8.4, and this seems to have even more problems. Thus I have been trying to use ghc 8.0.1 compiled from source. I think the red herring bit may apply to 32 bit builds, but I am attempting a 64 bit build. The problem may be related to the way modules are randomly relocated for security reasons, Fedora security policies, and confusion/bugs in the linker(s).
