I rebuilt rxvt-unicode with the patch and the urxvt segfaults at exit no
longer occurs. For me this is fixed.

Bug#981010: rxvt-unicode: urxvt segfaults at exit
Hi, I can reproduce this after a "xrdb -load /dev/null". However, I only seem to be able to reproduce it when I start urxvt via an i3 keybinding. If I start it via dmenu or by running "urxvt" from another terminal, I don't see a segfault in the logs. - Felix

FWIW I have the same error on (PE)RL_DESTRUCT_LEVEL here:
Program terminated with signal SIGSEGV, Segmentation fault.

Since it's in perl I would expect some extension to be required to have
that crash?
Anyway, it looks like opensuse has a patch for it since a couple of months
ago:

I do frequently find these messages in the syslog:

To reproduce under gdb:
