ruby leaks on "special" use of include

Stefan Lang

Just tried to do some fancy (probably inappropriate)
things with include:

module Foo
def foo
puts "foo called"
end
end

class MyClass
class << self
def include(*args)
include *args
end
end
def try_include
self.class.include Foo
puts "included Foo"
self.foo
end
end

obj = MyClass.new
obj.try_include

When I feed ruby with this code, it fills all available memory
(including swap) and the only way to stop it is per KILL.
BTW: "included Foo" is never printed.

% ruby -v
ruby 1.8.2 (2004-12-25) [i686-linux]

Is this a bug of ruby?

I hope that you have seen that ::include is recursive

Thanks for the tip! I must have been blind....

In the normal ruby way to do things, you should replace
"self.class.include Foo" by "self.extend Foo".

But, yes, leaking on self.class.include is a bug. If it must not be
possible, it should raise an exception instead.
