After significant testing, I can only reproduce the sefgault when ruby is compiled
with -O3.

I will try and produce a script which can trigger the segfault easily, but I
would advise anyone against compiling ruby with -O3 until this is nailed down.

I have been using gcc 3.4.1, but I don't know if the bug is due to or confined
to that most recent version of gcc.
