Can you please tell us more about your installation?  I tried to
replicate here but it still seems to work for me.  What version are you
using?

Also, if you run

	# mkdir -m 700 /var/crash/gotwebd
	# sysctl kern.nosuidcoredump=3

(or just kern.nosuidcoredump=2), can you get a backtrace out of it?


Thanks,
