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
in PHP7, we introduced a gc_additional_buffer. so I think >1000 make sense in this case.

Sorry, but now I'm not certain my patch is right.

Description:
------------
PHP 7 outputs wrong GC stats when compiled with -DGC_BENCH=1, because root_buf_length is not decreased when cyclic garbages are collected on GC.
Test script:
---------------
./sapi/cli/php </tmp/example1.php
where example1.php is shown at the following
http://www.php.net/manual/en/features.gc.performance-considerations.php
Expected result:
----------------
Root buffer length/peak should be <= 10000.
Actual result:
--------------
GC Statistics
-------------
Runs: 10
Collected: 99999
Root buffer length: 100001
Root buffer peak: 100006
