segmentation fault php7 symfony cli command using soap

Question

I am tring to upgrade to php7 and symfony3 from php5.6 and symfony2 resp. I have some symfony console commands which uses soap to request third party apis.

After upgrading to php7 and php7.0-soap, but command fails with segmentation fault. I tried debugging with gdb, below is the trace. Looks like this is the issue with php7.0-soap ? What is the solution ?

Program received signal SIGSEGV, Segmentation fault.

you can't use WSDL_CACHE_MEMORY (or WSDL_CACHE_BOTH) in PHP7 for the time being: https://bugs.php.net/bug.php?id=71931

use WSDL_CACHE_DISK instead by setting soap.wsdl_cache in php.ini, or - if you don't have access to php.ini - using ini_set:

ini_set('soap.wsdl_cache', WSDL_CACHE_DISK);
