I don't think it's so much about the correctness, it's rather the 
complicated features it supports, like metaprogramming. eval and 
bindings are causing problems, also promoting Fixnum to Bignum when it
doesn't fit is a problem. I also read somewhere that since you can 
replace any method in Ruby, all calls to a method needs to check if the 
method has been replaced.

Here's a blog that talks about the problems of optimizing Ruby [1]
