Previous Comments: ------------------------------------------------------------------------ [2021-06-17 09:46:36] requinix@php.net Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. It seems to hang for me after the START SCRIPT, with and without the cache. If there is a loop then the segfault could be a stack overflow trying to load the schemas (readily identifiable from a backtrace) however I don't think that would explain the EXC_BAD_ACCESS in strlen posted in that thread. ------------------------------------------------------------------------ [2021-06-17 09:02:56] arnaud dot lepeltier at cogifor dot Com Description: ------------ When instanciating a Soap Client for a large wsdl, I encounter a segmentation fault. This has been tested on php8.0 and php 7.4. Enabling/disabling the wsdl cache has no effect. increasing the memory limit has no effect initial ticket at: https://github.com/phpro/soap-client/issues/373 Test script: --------------- <?php echo PHP_EOL, "START SCRIPT"; $url = 'https://service-test.protel.io/services/ProtelApiService.ProtelApiServiceHttpsSoap12Endpoint?wsdl'; $client = new SoapClient($url, [ 'cache_wsdl'=>WSDL_CACHE_NONE ]); echo PHP_EOL, "SOAP CLIENT CREATED"; $client->__getTypes(); echo PHP_EOL, "GET TYPES DONE"; Expected result: ---------------- START SCRIPT SOAP CLIENT CREATED GET TYPES DONE Actual result: -------------- SOAP CLIENT CREATEDErreur de segmentation (core dumped) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81154&edit=1
