Hi Larry Uher,
I couldn't reproduce it, my crl was created successfully.
make sure you have the correct tagged input data, check "ls -laT zos.ca.*", make sure cat of this data is readable, the same with your config.
Can you also share with us your openssl.cfg, "env | sort" command output, also output of "openssl version" command for both old and new openssls
Thanks,
Alexander
