When a transaction is committed, C Xenstored will first check the quota is
correct before attempting to commit any nodes. It would be possible that
accounting is temporarily negative if a node has been removed outside of
the transaction. Unfortunately, some versions of C Xenstored are assuming
that the quota cannot be negative and are using assert() to confirm it.
This will lead to C Xenstored crash when tools are built without -DNDEBUG
(this is the default).
