Description changed by crockeea:

Old description:
...
In my directory ./ I have an empty file Foo.hs and a shared object file
mylib.so. From that directory in the shell,
$ ghci Foo *.so
    GHCi, version 7.8.2: http://www.haskell.org/ghc/  :? for help
    Loading package ghc-prim ... linking ... done.
    Loading package integer-gmp ... linking ... done.
    Loading package base ... linking ... done.
    Loading object (dynamic) mylib.so ... failed.
    <command line>: user specified .o/.so/.DLL could not be loaded
(mylib.so: cannot open shared object file: No such file or directory)
    Whilst trying to load:  (dynamic) mylib.so
    Additional directories searched: (none)
It's interesting that GHCi searches ./ and identifies the correct object
file, but then fails to load it. I have also tried the path ./*.so for
the GHCi option.
However, if I move mylib.so to a directory ./Temp,
$ ghci Foo Temp/*.so
loads without issue.
