New description:

 If I have the following module:

 {{{#!hs
 module Numeric.Integer ( is_prime_ats
                        ) where

 import           Foreign.C

 foreign import ccall is_prime_ats :: CInt -> CBool
 }}}

 and I attempt to open it in GHCi with the following

 {{{
 /opt/ghc/bin/ghci-8.4.2 -lnumbertheory -L../dist-newstyle/lib
 Numeric.Common
 }}}

 (with a file `libnumertheory.a` in `../dist-newstyle/lib`)

 I get a panic and a request to open a bug report. I am guessing that at
 the least this supposed to be a different error message.

 {{{
 GHCi, version 8.4.1.20180329: http://www.haskell.org/ghc/  :? for help
 ghc: panic! (the 'impossible' happened)
   (GHC version 8.4.1.20180329 for x86_64-unknown-linux):
     Loading archives not supported
 Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
 }}}
