Previous Comments: ------------------------------------------------------------------------ [2021-03-23 16:41:02] cmb@php.net Is this still happening with any of the actively supported PHP versions[1]? [1] <https://www.php.net/supported-versions.php> ------------------------------------------------------------------------ [2016-01-15 16:23:27] erik5 at pair dot com I believe this is a duplicate of #69184. I'm not exactly sure how SOAP is related to the FreeTDS library, but recompiling that without --enable-sybase-compat seems to resolve this. ------------------------------------------------------------------------ [2016-01-11 14:36:17] humbads at alum dot mit dot edu Here is the stack trace: Core was generated by `php'.

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. I can not reproduce this. ------------------------------------------------------------------------ [2016-01-10 20:22:16] humbads at alum dot mit dot edu Description: ------------ PHP crashes with a "bus error" message when calling the SoapClient constructor with any WSDL URL and no options. Everything works fine if WSDL caching is disabled. Strangely, everything also works fine when running the sample code from the command line like this: php -r 'var_dump(new SoapClient("http://www.webservicex.com/globalweather.asmx?wsdl"));' Here are my SOAP settings - everything should be default: php -i | grep -i soap soap Soap Client => enabled Soap Server => enabled soap.wsdl_cache => 1 => 1 soap.wsdl_cache_dir => /tmp => /tmp soap.wsdl_cache_enabled => 1 => 1 soap.wsdl_cache_limit => 5 => 5 soap.wsdl_cache_ttl => 86400 => 86400 Notes: * The test script is using a public/free WSDL URL. * Permissions on the /tmp folder are "drwxrwxrwt", and cached wsdl temporary files are being created there fine. * I think PHP is crashing because the error handler is not being triggered in my production code. Test script: --------------- <?php // Disable wsdl cache for workaround // ini_set('soap.wsdl_cache_enabled', 0); var_dump(new SoapClient("http://www.webservicex.com/globalweather.asmx?wsdl")); ?> Expected result: ---------------- object(SoapClient)#1 (2) { ["_soap_version"]=> int(1) ["sdl"]=> resource(17) of type (Unknown) } Actual result: -------------- Bus error ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71332&edit=1
