[Pkg-haskell-maintainers] Bug#790350: Bug#790350: ghc-mod: Crush problem of ghc-mod

[Daniel Gröber]

Hey,

thanks for the report! I can indeed reproduce this problem with the
version of ghc-mod in Debian and the latest version from upstream. I
added an issue upstream
(https://github.com/kazu-yamamoto/ghc-mod/issues/503) and will report
back when we have more information.
