[GHC] #11703: Segmentation fault/internal error: evacuate: strange closure type 15 with GHC.Generics

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. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11703 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
