Thanks for the report, but you are too late!
This bug is fixed in the forthcoming 3.30 release, which I hope to
release on Monday. The ChangeLog reads:
2. If ignore_target_hosts caused all hosts found from MX records to be
discarded, and there was more than one of them, Exim crashed.
The bug can also be fixed by this patch for Exim 3.22:
