I may have the same problem, on a newly installed raspian image on a RPi3B, all the recommended packages (except iwconfig, which is deprecated) were installed. Then create_ap was cloned and 'make install'ed and executed. At this stage internet access via eth0 thru 192.168.0.16 was trouble-free.

This was the output to the terminal screen:
root@MYHOSTNAME:/create_ap# create_ap --no-virt -g 192.168.0.16 wlan0 eth0 MYSSID MYPSK
WARN: brmfmac driver doesn't work properly with virtual interfaces and
it can cause kernel panic. For this reason we disallow virtual
interfaces for your adapter.

The Pi hung indefinitely at this point and an attempt (via ping) to reach reliable internet hosts failed.

These are the processes in memory at the time.

But i had solved this problem by upgrade my kernel ,I try open hostapd for a whole night ,and this problem is gone, so i suggestion you can try upgarde your kernel
