As you can see in the second example, there is a significant delay between
find's start and the first output. This is because more conditions are
specified, so fewer files match. But there is also a significant delay
between the first output and the program exit. This demonstrates that the
output is not being written at the end of the execution of the program.
You're likely also seeing the effect of stdio buffering. See
http://www.gnu.org/software/libc/manual/html_node/Stream-Buffering.html for a
brief explanation.
Lastly, findutils 4.2.27 (the release against which you made this bug report)
is very old now (it was released on 2005-12-06). Please upgrade.
