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
        
j...@lapr.js.berklix.net:/data/release/11.0-CURRENT/usr/obj/usr/src/sys/GENERIC
        amd64

/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 )

Cheers,
Julian
