My site crashed again. I have a core dump now. Here's a backtrace:

Any idea what the problem is?
BTW, I had never though about it, but I am running a debug build in the server, since that's the default of dub build.
(PS: does anyone remember how to change the core dump file name template, so that the core dump is not overwritten for every crash?)
