No problems on my side with a 128 MB file (not a device):
# cryptsetup -v luksFormat /tmp/testcrypt /dev/urandom
--keyfile-size=32 --cipher aes-cbc-essiv:sha256
# Command successful.
# cryptsetup -v luksFormat ~/testcrypt /dev/urandom --keyfile-size=32
--cipher aes-cbc-essiv:sha256
# Command successful.

Linux 4.15.0-rc9-00023-g1f07476ec143.

Some time ago you were building from not usual source code and your
kernel version from WARN is not unambiguous.

What is necessary to reproduce it?

Best regards,
Krzysztof
