Decompose the captured_cc code for investigation

Browse source 
I'm investigating SEGVs like 2715166621.
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.
