When I build it directly from Cabal it does not crash.
So this is most likely a bug in the GHC API. Perhaps Windows only. Perhaps already fixed, but we can't be sure without a way to reproduce (without relying on Eclipse FP or BuildWrapper). As mentioned by the BuildWrapper author in https://github.com/JPMoresmau/BuildWrapper/issues/49#issuecomment-67013339: What you should do is try to narrow the bug down by writing directly the GHC code. In https://ghc.haskell.org/trac/ghc/ticket/9845#no1 you can see I did that to expose another bug. The code buildwrapper used to invoke GHC is in the GHC module. Also note that the BuildWrapper Github page currently says: BuildWrapper is currently NOT maintained anymore. Feel free to fork and take up maintainership! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9877#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
