## #12734 — Kamesh Jayachandran — 2004-09-11T11:38:15+00:00

Hi All,
I could see in executor_globals_ctor calling zend_startup_constants
which allocates one hash table.
Later to free this hash table zend_shutdown_constants is called from
zend_shutdown rather than executor_globals_dtor.
This may not cause a memory leak in Non ZTS environment where
zend_shutdown and executor_globals_dtor are called only once and the
current free up by calling zend_shutdown_constants from zend_shutdown
won't cause any memory leak.

In case of ZTS environment every thread calls executor_globals_ctor and
only the main thread causes zend_shutdown and hence only main thread
EG(zend_constants) are freed whereas other threads EG(zend_constants)
are not freed.

Correct me if I am wrong.

With regards
Kamesh Jayachandran
