Description: Loading a dynamic module more than once causes a linker failure with the following message: ''' /usr/bin/ld.gold: error: cannot find -lghc_2 collect2: error: ld returned 1 exit status `gcc' failed in phase `Linker'. (Exit code: 1) *** Exception: ExitFailure 1 ''' `-lghc_2' sometimes is `-lghc_5' or other numbers. Steps to Reproduce: 1) Clone above repo. 2) `stack build` 3) `stack exec mwe-exe` The repo code will use the GHC API to load a string from the file contained in scripts/ named `val'. There are three functions defined in src/Lib.hs. `anotherFunc' should behave normally. `someFunc' should display the bad behavior. Notes: - When using `intero`: intero must be restarted if this bug is encountered at the prompt, or else you will keep getting it over and over again. - I could not figure out how to load it up without using the `-dynamic' flag, but that should probably be checked out too. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14856 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
