Hi,

The folliowing fails for me on current master:

#include <libguile.h>

static void
inner_main (void *closure, int argc, char **argv)
{
 scm_c_use_module("system repl repl");
 scm_c_eval_string("(start-repl)");
}

int
main (int argc, char **argv)
{
 scm_boot_guile (argc, argv, inner_main, 0);
 return 0; /* never reached */
}

I get:

Some code along these lines has been working OK on 2.0+ for a while,
not quite sure when it broke.

Sorry we didn't get this in time for 2.0.3.  It is now fixed on
stable-2.0, I think.
