For example, the following code leaks:
class MyRipper < Ripper
def initialize(src, &blk)
super(src)
@blk = blk
end
def warn(msg, *args) = @blk.call(msg)
end
$VERBOSE = true
def call_parse = MyRipper.new("if true\n end\n") { |msg| return msg }.parse
10.times do
500_000.times do
call_parse
end
puts `ps -o rss= -p #{$$}`
end
