Bug #70079 [Com]: Segmentation fault after more than 100 SoapClient calls

Edit report at https://bugs.php.net/bug.php?id=70079&edit=1 ID: 70079 Comment by: dmifedorenko at gmail dot com Reported by: dmifedorenko at gmail dot com Summary: Segmentation fault after more than 100 SoapClient calls Status: Open Type: Bug Package: Unknown/Other Function Operating System: Linux vm 3.13.0-37-generic #64-U PHP Version: 7.0Git-2015-07-15 (Git) Block user comment: N Private report: N New Comment: Minimal source code to reproduce problem: --- <?php class JiraSoapClientEx extends SoapClient { } $jiraClient = new JiraSoapClientEx('http://aux.srv.loc:82/rpc/soap/jirasoapservice-v2?wsdl'); $token = $jiraClient->login('admin', 'XXXX'); for ($i = 1;$i<=150;$i++) { $jiraClient->getIssue($token, "BAZAR-240424"); } --- If I change 150 to 80 for example the code will work. Only after about 100 calls to SoapClient the script will fail. Jira server is still private, we try to find way to open it in public, but that is not easy task.

Previous Comments: ------------------------------------------------------------------------ [2015-07-15 09:50:28] laruence@php.net hmm, this kind of backtrace(segfault in zend_mm) implies that the memory is corrupt by some codes before, which make the backtrace kind of useless. we need find who corrupt it.. so.. if no reproduceable scripts ,, no much things we can do. :< thanks ------------------------------------------------------------------------ [2015-07-15 06:59:55] dmifedorenko at gmail dot com Sorry but server is not public, it works in locale network only. I cant share full source code of client due to copyrights. Minimal code example useless without public soap server. Or not?
