Subject: rb_rescue2 crashes 1.9.0-0

good day all,

the following rb_rescue2 works with old versions - tested with 1.8.5 and 1.8.6. but crashes 1.9.0-0. 
something's wrong with the code or is it a problem in 1.9.0-0's rb_rescue2?

#include <ruby.h>
#include <stdio.h>

#ifndef RSTRING_PTR
#define RSTRING_PTR(o) RSTRING(o)->ptr
#endif

static VALUE eval_failed(VALUE v, VALUE exc)
{
    printf("eval_failed\n");
    return exc;
}

int main() {
    VALUE retv;
    int i;
    char *codes[] = {
        "de foo; puts \"in foo()\"; end",
        "1/0"
    };
    
    ruby_init();
    ruby_init_loadpath();

    for (i = 0; i < 2; i++) {
#ifdef USE_RB_STR_NEW2
        retv = rb_rescue2(rb_eval_string, rb_str_new2(codes[i]), eval_failed, Qnil, rb_eException, 0);
#else
        retv = rb_rescue2(rb_eval_string, (VALUE)codes[i], eval_failed, Qnil, rb_eException, 0);
#endif
        if (rb_obj_is_kind_of(retv, rb_eException))
        {
            VALUE msg = rb_funcall(retv, rb_intern("message"), 0);
            printf("Error: %s\n", RSTRING_PTR(msg));
        }
    }

    ruby_finalize();
    exit(0);
}

rgds,
Edwin
