Description:
------------
When calling a method by _soapCall, PHP 7.3.1 (XAMPP) crashes without logging any error, even in the framework (CodeIgniter) or in isolated script, returning ERR_CONNECTION_RESET error.

PHP log in XAMPP don't have anything too.

It doesn't happen with every wsdl and not with every method.

Doing the same request by SoapUI, everything goes fine.
Doing the same request in PHP 5.6.31 (WAMP), everything goes fine.

OBS: Sorry about all these catches, I was desperate for handling some error.

Test script:
