Compiled Haskell program giving segfault

Compiling with cabal

both the GHC-Options: -dcore-lint -debug

program and working with +RTS -DS

, I get this:

cap 0: initialised
goog-closure: internal error: ASSERTION FAILED: file rts/sm/Sanity.c, line 87

    (GHC version 7.6.3 for x86_64_unknown_linux)
    Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
Aborted

      

        
        
        
      

    

Most likely the GC, adding some fingerprints to deactivate the offending statement, just move the point of failure. I know I need to find a small reproducible test case. It is now 100% reproducible, but not quite small. I leave this here for those who can point me in an easier direction if possible. Additional Information:
