AV in client library when working with BLOBs

Created: 12/Oct/08 02:10 PM   Updated: 08/Nov/09 08:05 PM

Affects Version/s: 2.1.0, 2.5 Alpha 1, 2.1.1, 2.1.2
Fix Version/s: 2.5 Beta 1

Environment: Any

 Description  « Hide
The bug was reported by Dmitry Kovalenko. When transaction is closed, but blob, opened in it, remains opened, any attempt to work with it later results in unpredictable behavior, including AV.

The reason is that redirector closes all related blobs, but yValve data structures keep pointers to invalid any more objects.
