* Priority: Normal
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN

Reproducable with the same script from: https://bugs.ruby-lang.org/issues/19894
``` ruby
10.times do
20_000.times do
$c = Class.new do
def foo; end
end
$m = Module.new do
refine $c do
def foo; end
end
end
Class.new do
using $m
def initialize
o = $c.new
o.method(:foo).unbind
end
end.new
end
puts `ps -o rss= -p #{$$}`
end
