Are you able to call the ocaml code from the C ? I think this is rather 
different from calling C libs from a standalone OCaml code.
In my case, i mix the 2 langages in this way :

let cmain_ocaml n = try

let _ = Callback.register "cmain_ocaml" cmain_ocaml

in a cmain_cpp.cpp , where there is the "real" main() function:
 static value * cmain_closure = NULL;
 if (cmain_closure==NULL)
   cmain_closure = caml_named_value("cmain_ocaml");
 result = Int_val(callback(*cmain_closure,Val_int(n)));

It crashses when calling :  callback(*cmain_closure...)

All is compiled into native solaris object code.
The same thing works perfectly on solaris/sparc.
