Peter Zhu 10574857ce Fix memory leak in Regexp capture group when timeout
[Bug #20650]

The capture group allocates memory that is leaked when it times out.

For example:

    re = Regexp.new("^#{"(a*)" * 10_000}x$", timeout: 0.000001)
    str = "a" * 1000000 + "x"

    10.times do
      100.times do
        re =~ str
      rescue Regexp::TimeoutError
      end

      puts `ps -o rss= -p #{$$}`
    end
