starting repl from C broken

starting repl from C broken

[Tristan Colgate]

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:

Backtrace:

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