Edit report at https://bugs.php.net/bug.php?id=65784&edit=1 ID: 65784 Updated by: felipe@php.net Reported by: r dot wilczek at web-appz dot de Summary: Segfault with finally -Status: No Feedback +Status: Open Type: Bug Package: *General Issues Operating System: Linux PHP Version: 5.5.4 Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2013-10-15 11:54:52] php-bugs at lists dot php dot net No feedback was provided. The bug is being suspended because we assume that you are no longer experiencing the problem. If this is not the case and you are able to provide the information that was requested earlier, please do so and change the status of the bug back to "Re-Opened". Thank you. ------------------------------------------------------------------------ [2013-10-03 11:53:28] r dot wilczek at web-appz dot de Here you are ... /* @var $sql string */ /* @var $expr SomeInterface */ /* @var $ctxt AnotherInterface */ $trx = $this->ctxt->beginTransaction(); // an interface $memento = $this->ctxt->getMemento(); // can be anything try { $this->ctxt->persist(); // don't return or throw exception return $this->execute($expr, $sql); // return scalar[] or throw exception } finally { $this->ctxt->setMemento($memento); // don't return or throw exception $trx->rollback(); // don't return or throw exception } Don't know, if this helps. What I forgot to mention was, that the segfault occurs, when there is an exception thrown from within the try-block. ------------------------------------------------------------------------ [2013-10-01 22:58:15] nikic@php.net Could you please post the code as it is actually used (just the part containing the finally)? Your backtrace indicates that the segfault happens during an argument send, but your code samples do not include any function calls with arguments. ------------------------------------------------------------------------ [2013-09-29 12:26:34] r dot wilczek at web-appz dot de (The second core-dump is created without xdebug, to keep things simple) ------------------------------------------------------------------------ [2013-09-29 12:25:34] r dot wilczek at web-appz dot de #0 0x0000000000a41895 in zval_delref_p (pz=0x0) at /root/php-5.5.4/php-5.5.4/Zend/zend.h:409 #1 0x0000000000a4330c in zend_pzval_unlock_func (z=0x0, should_free=0x7fffa8aa9e90, unref=1) at /root/php-5.5.4/php-5.5.4/Zend/zend_execute.c:72 #2 0x0000000000a4341b in _get_zval_ptr_var (var=4294967232, execute_data=0x7f1fceaa5098, should_free=0x7fffa8aa9e90) at /root/php-5.5.4/php-5.5.4/Zend/zend_execute.c:186 #3 0x0000000000a63e15 in ZEND_SEND_VAR_NO_REF_SPEC_VAR_HANDLER (execute_data=0x7f1fceaa5098) at /root/php-5.5.4/php-5.5.4/Zend/zend_vm_execute.h:13081 #4 0x0000000000a480cf in execute_ex (execute_data=0x7f1fceaa5098) at /root/php-5.5.4/php-5.5.4/Zend/zend_vm_execute.h:363 #5 0x0000000000a48157 in zend_execute (op_array=0x2e129f0) at /root/php-5.5.4/php-5.5.4/Zend/zend_vm_execute.h:388 #6 0x00000000009f6785 in zend_call_function (fci=0x7fffa8aaa100, fci_cache=0x7fffa8aaa0d0) at /root/php-5.5.4/php-5.5.4/Zend/zend_execute_API.c:939 #7 0x000000000076285c in zim_reflection_method_invokeArgs (ht=2, return_value=0x2e3b2d0, return_value_ptr=0x0, this_ptr=0x2e3b450, return_value_used=1) at /root/php-5.5.4/php-5.5.4/ext/reflection/php_reflection.c:3018 #8 0x0000000000a489de in zend_do_fcall_common_helper_SPEC (execute_data=0x7f1fceaa49e8) at /root/php-5.5.4/php-5.5.4/Zend/zend_vm_execute.h:550 #9 0x0000000000a491b0 in ZEND_DO_FCALL_BY_NAME_SPEC_HANDLER (execute_data=0x7f1fceaa49e8) at /root/php-5.5.4/php-5.5.4/Zend/zend_vm_execute.h:685 #10 0x0000000000a480cf in execute_ex (execute_data=0x7f1fceaa49e8) at /root/php-5.5.4/php-5.5.4/Zend/zend_vm_execute.h:363 #11 0x0000000000a48157 in zend_execute (op_array=0x7f1fcead9b60) at /root/php-5.5.4/php-5.5.4/Zend/zend_vm_execute.h:388 #12 0x0000000000a0a27f in zend_execute_scripts (type=8, retval=0x0, file_count=3) at /root/php-5.5.4/php-5.5.4/Zend/zend.c:1318 #13 0x0000000000976e9e in php_execute_script (primary_file=0x7fffa8aad7a0) at /root/php-5.5.4/php-5.5.4/main/main.c:2489 #14 0x0000000000ab7ac7 in do_cli (argc=5, argv=0x263beb0) at /root/php-5.5.4/php-5.5.4/sapi/cli/php_cli.c:994 #15 0x0000000000ab8bff in main (argc=5, argv=0x263beb0) at /root/php-5.5.4/php-5.5.4/sapi/cli/php_cli.c:1378 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
