Hey,
the underlying filesystem is a tmpfs for me as well:
# uname -a
Linux 4.14.0-3-amd64 #1 SMP Debian 4.14.13-1 (2018-01-14) x86_64
# mount | grep /tmp
none on /tmp type tmpfs (rw,nosuid,nodev,noatime,nodiratime)
# modprobe aufs debug=1 \
&& mkdir /tmp/{ro,rw,mount} \
&& touch /tmp/ro/bla \
&& mount -t aufs -o dirs=/tmp/rw=rw:/tmp/ro=rr+wh aufs /tmp/mount \
&& ls /tmp/mount ; \
ls /tmp/mount
bla
bla
I get no segfault for the call still so there has to be another reason...
Best regards,
Jan
