Avast!

The (scary long) SETUP_CONTROL macro is making a dangerous assumption.

...
text = ATTR(self_t->attr, text); \
if (!NIL_P(text)) { \
  msg = RSTRING_PTR(text); \
  len = (RSTRING_LEN(text) * 6) + 32; \
} \
...

Yup, if there's an ATTR there, lets just assume it's a string. "Hey Ruby! What's that string?" ... "--> Boom?!"

Someone more up on their Ruby C API could probably write some code that tests to see if it's really a string, and if not, go ahead an call to_s on it or something.

Hope that helps.

Oh, as a workaround, you could call to_s yourself. :P
