Hi, Alright, as usual my "perfectly working code base" wasn't working perfectly after all.
What happened was that I defined (and manually called) a few __destruct methods on instances that shouldn't be destructed yet. I think this caused some kind of invalid pointers. I am still unsure about why the code worked fine before the upgrade (maybe something changed in the garbage collection). I'd love to share my "isolated case", but it turns out it wasn't much isolated. I will try to isolate it some more, since now the required code is rather huge. I'm going to try to recreate the error in a single file tomorrow, maybe it's interesting to see what's actually going on. The server guys are also going to install the debug tools. I'll add more information tomorrow, but as I've said, it might be a problem in my code. (Although even in that case it shouldn't segfault.) Greetings, Thijs
