`app process exited on signal 11 (core dumped)` after completeing request

[bandogora]

The C application dumps its core after completing a request response. This happens every time.

This doesn't actually affect much since the request is completed and Unit starts a new process when a new request is received.

I'm not sure if this is an app issue, or a Unit issue.

This seems to be related to using the unit response buffer.

The issue doesn't happen when calling nxt_unit_response_write.

Probably related to nginx/unit#1125
