# 4695 Transaction Rollbacks Can Cause an AV with Certain Combinations of Row Inserts and Deletes

---

I think I have found a trouble in ElevateDB.

Scenario 1 (works as excpected):

Table opened
Start transaction (restricted or not)
Delete some records from this table
Add some records from this table
Generate an exception based on business rules that will produce a database rollback

Scenario 2 (fires an AV exception)

Table closed
Start transaction (restricted or not)
Open table
Delete some records from this table
Add some records from this table
Generate an exception based on business rules that will produce a database rollback.

I copied the ElevateDB source code to the project folder and the AV fires happens in FTableManagers.Rollback line on procedure TEDBLocalDatabaseManager.Rollback;
