Yeah, I know, sorry. I just posted so you guys know while I'm working on a test case. Hmm, when I'm looking at the backtrace it might be another problem. It might be a problem with array appending or the GC, in this method:

https://github.com/jacob-carlborg/orange/blob/master/orange/xml/PhobosXml.d#L764

The above method is the last step in the backtrace that is part of my code.

This is the start of the backtrace:
