Description:
------------
So this is PHP 7.3 BC break and I can't find it in https://www.php.net/manual/en/migration73.incompatible.php

Constructing SoapClient with no arguments can no longer be caught. It's very likely other classes are affected as well. Where can I read about this BC break?

PS: Sorry for not selecting soap package when creating issue, but I don't see it anywhere in a list

Test script:
---------------
try { new SoapClient(); } catch (Throwable $e) {} // PHP 7.2 no output, PHP 7.3 result:  Warning: SoapClient::SoapClient() expects at least 1 parameter, 0 given in php shell code on line 1
