Yesterday I updated to to last daily build (4156), no more AV happened. I will try to make some more stress tests, will update if something happens. As I wrote before, problem was not stable - it happens after some work time on the same connection, and on some selected queries only - i.e. some other queries on the same connection were OK.

Hello Alexey,

could you provide a small sample application that triggers the problem and maybe a create script for a database?

Best regards,

Jan

Hi !

With the last 7.3 build found a problem: AV in TZAbstractResultSetMetadata.ReadColumnByRef in SysFreeMem procedure call.

TZConnection itself is shared between several queries, so problem appears with some query types, while some others still work ok. Also, problem appears after some operation time, but time when first AV happens is random - it may happen in few seconds, but may appear after several hours.

Preliminary, calls like standard SELECTs are working ok, while calls like SELECT * from some_stored_procedure() are causing problems.
