Decompose the captured_cc code for investigation
I'm investigating SEGVs like https://github.com/ruby/ruby/runs/2715166621?check_suite_focus=true.
Because a lot of things are going on on this line, it's hard to identify
the cause, especially because we can't get the core file of the failures.
Therefore I intentionally increased the number of lines for
investigation.
