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.
