freebsd stable - Feb 2021 - latest stable13.0-ALPHA3 can not start varnish anymore.

I just updated my FreeBSD 13.0-APLPHA3 to the latest revision and now i 
can not start varnish anymore.
This is on two machines.

if i start varnish it errors out as the startup script does a config 
file check.
If i try to do a test of the config file i get the following error.

root at jhost002:~ # varnishd -C -f /usr/local/etc/varnish/default.vcl
Error: Cannot create working directory '/tmp/varnishd_C_dwbl7mn/': Is a 
directory
Error: Cannot create working directory (/tmp/varnishd_C_dwbl7mn/): No 
error: 0
(-? gives usage)
root at jhost002:~ #

This is on:
FreeBSD jhost002.mydomain.nl 13.0-ALPHA3 FreeBSD 13.0-ALPHA3 #35 
stable/13-c256281-gc415d0df47fc: Mon Feb? 1 17:04:49 CET 2021 
root at srv-01.home.local:/usr/obj/usr/src/amd64.amd64/sys/KRNL amd64

I did not update the package or installed any other software besides the 
buildworld.

regards,
Johan

Without the check, varnish fails to start all together.

I have tested this on a new machine updated to the same revision, same 
result.

I have tried some bisecting as far as my understanding of git goes. I do 
not know which one is the latest, but on these revisions varnish works.
