Mike Beckerle commented on DAFFODIL-2662:
-----------------------------------------
Can be reproduced (for those with access) using
[email protected]:mbeckerle/p8-schema.git branch
daf-2662-deadlock.
Suggests the changes in DAFFODIL-2626 (note not a typo. This one is 2662, that
one is 2626) aggravated the unparser deadlock behavior for this test.
We may in fact need the "just turn off alignment fill" flag discusssed in that
(now closed) ticket.
