Yes, I saw that too - I'll file a defect against it. I'll also file one 
about having to do the fake argc/argv.

Anyway, just for completeness and for anybody else looking for a 
workaround, here is my working test program.

Graham

    #include <ruby.h>

    int
    main(int argc, char *argv[])
    {
         RUBY_INIT_STACK;
         ruby_init();
         static char* args[] = { "ruby", "/dev/null" };
         ruby_process_options(2, args);

         rb_eval_string("p Mutex.new.methods");

         return 0;
    }
