Following #4864, we began using Saxon-C PE edition to write custom XSLT extensions in PHP.

I first used an evaluation license and used v1.2.1 on my own workstation (Debian 10). I experienced weird crashs but it seemed to me they were due to either or/and (I would say OR: 1) execution of php script in home directory 2) PHP extnesion function name was too long. So a shorter one in /tmp or /opt for example was OK. I still need to take some time to report that to you with more details.

Then, we wanted to deploy on our dev server (Debian 10) with a paid PE license. No luck this time, it fails at all times.

With 1.1.2 (we still use this version due to blocking bug: #4371
