Crash under Debian 9 / PHP 7.0 #343

Closed frachonl closed 6 years ago

Using as Jenkins documentation, we upgraded recently to PHP 7.0, and face a crash now

What could I provide to help resolving ?

Stracing the real Jenkins call, here is the "crash" just after correct results:

Any idea ?

Your PHP Environment is broken, as a CORE warning cannot be triggered from userland code:

ErrorException: E_CORE_WARNING Location: Unknown (Line 0)

Module 'PDO' already loaded

You somehow try to load the pdo.so twice, which PHP doesn't like. phpDox checkes on shutdown if any unhandled errors occured but doesn't know how to handle CORE Warnings (yet).

This technically is not a bug in phpDox.

Ok, will investigate that way. Thanks
