Comment (by albertov):

 I've narrowed the problem to a specific source file and a specific commit.
 Since
 [https://github.com/meteogrid/sigym4-geometry/commit/2b00e8f5052cc392724659079535b453034f1d9a#diff-4
 these changes] where made to the `Types.hs` module GHC 7.10 starts
 consuming all available RAM until the OS kills it when trying to compile
 it.
