Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
This seems to be caused by the Valgrind's strange behavior. Valgrind
terminates
the program immediately when the signal was sent during a interruptible system
call. It eventually fails to call necessary shutdown functions, and results in
massive leaks.

If use the RFC routing example, starting the server as "php -S localhost:8000
routing.php" and browse for an existing JPG files, I see:
PHP Development Server is listening on localhost:8000 in
/home/cjones/public_html ... Press Ctrl-C to quit.

If I repeat this with valgrind, I see the same output. After ^C, I get 5.5K
loss records reported by valgrind.

Description:
------------
When using the CLI server, more than one access results in a huge amount of
still reachable memory.
Test script:
---------------
touch t.php
valgrind --leak-check=full --show-reachable=yes php -S localhost:8080
[browser] /t.php
[browser] /t.php
<ctrl+c>
Actual result:
--------------
55k lines of segments that are apparently still reachable
