ps_call_handler() set PS(in_save_handler) around call_user_function() with no protection against zend_bailout() from inside a userland save handler callback; a bailout in open/read/write/close/etc. left the flag sticky so the shutdown flush falsely reported "Cannot call session save handler in a recursive manner" and skipped the pending handler calls. Wrap the invocation in zend_try/zend_catch that clears the flag and falls through to argv cleanup before re-bailing out. Sibling audit: all userland handler entry points funnel through ps_call_handler(), so this single guard covers every path; PS_OPEN_FUNC()/PS_CLOSE_FUNC() already carry outer try/catch for their own retval/status cleanup and remain as is. bug60634_error_3.phpt and bug60634_error_4.phpt expected the old sticky-flag warning at request shutdown and are updated to expect the now-working close handler instead.

ps_call_handler() set PS(in_save_handler) around call_user_function() without zend_bailout() protection, so a fatal error in a userland save handler left it sticky; shutdown warned falsely of recursion, skipped pending calls, losing session data. The call now runs under zend_try/zend_catch clearing the flag, falling through argv cleanup before re-bailing. All userland entry points go through ps_call_handler(), covering open/read/write/destroy/gc/create_sid/validate_sid/update_timestamp via one guard. The bug60634 tests now expect the working close handler instead of the sticky-flag warning.
