any script to reproduce this?
 [2015-09-08 06:49 UTC] sixd@php.net 
From the reporter:
"This issue is reproducible only when run the test through "gmake test TESTS=%" command and with valgrind option "--leak-check=full".
Basically leak occurs while php attempts to load the php config ini file, i.e., before it loads actual testcase.

Please configure the run-tests.php to run Valgrind and make sure add "--leak-check=full" in run-test.php in valgrind command present in line number 1882, 1884.
Then run test in ext/date as follow:
gmake test TESTS=ext/date

Even first testcase ext/date/tests/002.phpt will LEAK with the reported memory leak (definitely lost category)."
