Segmentation fault on 5f37e0c7
I'm experiencing a segmentation fault in previously working code compiled with GHC master (5f37e0c7). This occurs with several executables in bayes-stack (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.
