Has anyone else noticed ctfmerge either 
- temporarily sucks the life out of the machine,
- or crashes 
cd /usr/src; make buildworld ; make buildkernel
	linking kernel.full
	ctfmerge -L VERSION -g -o kernel.full ...
No rponse from these:
  Attempt to start new xterm to host (to run top) fails,
  Attempt to Control Z suspend the job in existing xterm is ignored,
  Stroking keypad (aka mouse wobble) ignored
  Screen stayed black (as it was before cos xdm was running & no human using it)
  No disk activity.
Eventually laptop fan ran a bit faster for a bit (BIOS ?)
I had to power off laptop to reboot.

I've seen it a few times in recent weeks with various recent current.

uname -a
	FreeBSD lapr.js.berklix.net 11.0-CURRENT FreeBSD 11.0-CURRENT
	#4 r298975M: Wed May  4 14:59:04 CEST 2016
	jhs at lapr.js.berklix.net:/data/release/11.0-CURRENT/usr/obj/usr/src/sys/GENERIC

/usr/src it crashed building is at svn 299060	OK I now have newer here.

I have nothing to debug in /var/crash as
	swapinfo		2 355 200 1K-blocks
	bsdlabel /dev/ada0s1	4 710 400 

	dmesg real memory  	3 221 225 472 (3072 MB)
	dmesg avail memory 	2 759 401 472 (2631 MB)
So ready for next one, I'll re bsdlabel the partition, 
(less risky than keeping a 4G ram stick in with /etc/rc.conf dumpdev=/dev/da0 )
