Yes, but you have to do

    PUSH_TAG();
    if ((state = EXEC_TAG()) == 0) {
        rb_requir(...)
        rb_eval_string(...)
    }
    POP_TAG();

or use rb_protect utility function.  My modified code was

static VALUE LoadFile0(VALUE filename)
{
	return rb_require((const char *)filename);
}

void Ruby::RubyImpl::LoadFile(const char *filename)
{
        int state;

	rb_protect(LoadFile0, (VALUE)filename, &state);
        // you can check state==0 for success.
}
