 I'm experiencing a segmentation fault in previously working code compiled
 with GHC master (5f37e0c71ff4af8539c5aebc739b006b4f0c6ebf). This occurs
 with several executables in bayes-stack[1] (BenchLDA and RunST).

 The easiest reproduction case is BenchLDA, which can be run without any
 external data (although doesn't get built by the cabal file). In the case
 of BenchLDA, gdb says that the crash is occurring in c6FD_info which seems
 to fall within BayesStack.Models.Topic.Types, although -ddump-simpl
 doesn't seem to give any hints as to which function this is.
