I assume you mean 4.90.1, I just added exim-4.91_rc1 to the tree, which may solve your problem. https://lists.exim.org/lurker/message/20180314.204626.c1c63267.en.html It may be the crash on dnsdb lookups, but that's just a wild guess.
Sorry, 4.90.1 version, of course And yes, Exim uses DKIM acl
I would appreciate if you could give 4.91 a try
