 Running a compiled executable on some complex input is causing this:

 postparse.exe: internal error: evacuate: strange closure type 5101248
     (GHC version 7.10.2 for x86_64_unknown_mingw32)
     Please report this as a GHC bug:
 http://www.haskell.org/ghc/reportabug

 Running under Cygwin on Windows 8.1, 64.

 I suspect this may be a memory-related issue, but it's hard to diagnose as
 postparse.exe is operating in a larger ecosystem.
