undefined symbol: DataziSafeStore_zdszdfApplicativeNoLoggingTzuzdszdfMonadResourceT_closure

Hi, when compiling a program I get this message:

ghc: panic! (the 'impossible' happened)
      (GHC version 7.10.3 for x86_64-unknown-linux):
    	Loading temp shared object failed: /tmp/ghc4185_0/libghc_82.so: undefined symbol: DataziSafeStore_zdszdfApplicativeNoLoggingTzuzdszdfMonadResourceT_closure

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

The same program compiled fine before, not sure what might be causing it.. happy to provide more info if you tell me what will help.

Here is a list of pragmas we are using in the file where it crashed:

{-# LANGUAGE EmptyDataDecls             #-}
{-# LANGUAGE FlexibleContexts           #-}
{-# LANGUAGE FlexibleInstances          #-}
{-# LANGUAGE GADTs                      #-}

{-# LANGUAGE TypeFamilies               #-}
{-# LANGUAGE DeriveGeneric               #-}

and also it's worth mentioning the code is using the DB access library "peristent".

Well, the problem went away after doing a clean build (stack clean...). So not sure it this counts as a GHC bug or not.

changed the description

It's very hard to say; without a reproducible testcase it's hard to do much about this. I'm going to close this but if you observe this sort of failure again feel free to reopen.
