Thanks, I'll give it a try along with your other questions and report back.
For clarity, the repro steps dropped a step. They should have included the make command:
$ dd if=/dev/urandom of=test_file bs=1M count=10240
$ desync make test_file.caibx test_file
$ sudo bash -c "echo 3 > /proc/sys/vm/drop_caches"
$ desync verify-index test_file.caibx test_file
