Description
When the file is overwritten by the COPY method under the following conditions, content of copied file is not correct.
- OS: CentOS 7.4
- Nginx Version: 1.12.2

I have attached the configuration file, the access log, and the error log at the debug level.
The Overwrite header is not specified (The superscription has been permitted).
I expected that the content of "source/copy.txt" and "dest/copy.txt" were equal as a result of COPY.
However, the top part of "dest/copy.txt" is only replaced by "source/copy.txt" .
What should I do to get the expected result?
