 Reproduced issue on both Windows-7/GHC-7.10.3 and Linux-4.1.15/GHC-7.8.4
 Seems to probably be a problem with GHC.Generics and the runtime.

 Windows/GHC-7.10.3 states:
 internal error: evacuate: strange closure type 15
 (GHC version 7.10.3 for x86_64_unkown_mingw32)
 Please report this as a GHC bug: httpL//www.haskell.org/ghc/reportabug
 This application has requested the Runtime to terminate it in an unusual
 way.
 Please contact the application's support team for more information.

 Linux/GHC-7.8.4 states:
 Segmentation fault

 Behavior varies based on CSV input file size, a CSV file with header with
 1 to 4 rows works. A CSV with a header and more than 10 rows segmentation
 faults imediatly. Inbetween 4 to 10 sometimes runs forever, works, or
 segmentation faults.

 The test case uses Cassava and GHC.Generics and some derived instances to
 read a CSV file with a record data type with many fields.
