Hi

starting wit a running nginx/1.9.10 on linux/64

simple build/upgrade to nginx/1.9.11; same config as before

no errors in build

	nginx -v
		nginx version: nginx/1.9.11

but,

	systemctl start
		nginx.serviceJob for nginx.service failed. See "systemctl status nginx.service" and "journalctl -xn" for details.

	systemctl status nginx.service -l
		nginx.service - The nginx HTTP and reverse proxy server
		   Loaded: loaded (/etc/systemd/system/nginx.service; enabled)
		   Active: failed (Result: signal) since Tue 2016-02-09 07:09:47 PST; 24s ago
		  Process: 4509 ExecStartPre=/usr/local/sbin/nginx -t -c /usr/local/etc/nginx/nginx.conf (code=killed, signal=FPE)
		 Main PID: 7589 (code=exited, status=0/SUCCESS)

	nginx -t -c /usr/local/etc/nginx/nginx.conf
		Floating point exception

in syslog

	Feb  9 07:11:07 jimsweb kernel: [393917.665398] traps: nginx[4679] trap divide error ip:41a95e sp:7ffef4fcbd00 error:0 in nginx[400000+ed000]

dropback to 1.9.10 works fine

if there's other info that'll help, let me know.
