Bug Free

Hi,

Ruby 1.9.0 crashes on the following code:
======================
class Foo
def Foo.get
return true if defined? @@x && @@x <= 0
end
end
Foo.get
======================

This is the version:
clay:~/tests/ruby/bugs$ ruby1.9 -v
ruby 1.9.0 (2007-12-25 revision 14709) [i486-linux]

This is the stack trace:
clay:~/tests/ruby/bugs$ ruby1.9 crash.rb

Your program works fine for me on 1.9.1-preview2, under Ubuntu Hardy.

$ ruby19 crash.rb
$ ruby19 -v
ruby 1.9.1 (2008-12-01 revision 20438) [i686-linux]
$

So maybe you just need to upgrade.
