The problem however appears earlier.
It seems that the zval structure ps_globals.http_session_vars points at
is freed and allocated elsewhere, but ps_globals.http_session_vars
points to the old location, so when it comes to
php_session_save_current_state (#1),
Z_ARRVAL_P(PS(http_session_vars)) holds some meaningless value.
