This is not a bug, but the expected behavior.
The file you attached does not have a '\n' character
at the end of the last line.
Technically, 'wc' counts the number of '\n' characters,
not the number of appeared lines.
This is explained here:

As such, I'm marking this as not-a-bug, but discussion can
continue by replying to this thread.
