I was able to install gcc-7 on a Fedora 25 test VM and got the following
from a test run:

# ./zdtm.py run -f h -a --keep-going
################### 2 TEST(S) FAILED (TOTAL 293/SKIPPED 102) ###################
 * zdtm/static/deleted_unix_sock(unknown)
 * zdtm/static/del_standalone_un(unknown)
##################################### FAIL #####################################

So it seems most of the test are working. Not sure why those 2 failed.

And all test passed for: ./zdtm.py run -f ns -a --keep-going
