Comment:

 I'm still experiencing this issue with ghc-7.8.3-x86-64-unknown-linux and
 gcc-4.8.2.

 Consider the following C file, mul.c:

 {{{#!c
 //zipWith (*)
 void mul (int* a, int* b, int n) {
   int i;
   for(i = 0; i < n; i++) {
     a[i] = a[i]*b[i];
   }
 }
 }}}

 At the terminal (where Foo.hs is empty):
 {{{
 > gcc -c mul.c
 > gcc -shared -o mylib.so *.o
 > ghci Foo *.o
 GHCi, version 7.8.3: http://www.haskell.org/ghc/  :? for help
