GHCi panics when attempting to load archives
If I have the following module:
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.Integer
(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
If I instead place a shared library (i.e. libnumbertheory.so
) in ../dist-newstyle/lib
) then this does not panic.
