Driver crashing on many temporary tables?

Hello,

we have a problem with psqlODBC v8.2.300 (maybe some older releases as well) and above - up to v8.3.400.
Some large operations/transactions can cause the driver to crash - obviously depends on the size of the db as well though. It seems to happen on the same query on the same client - but different from the other clients/servers/days. Operations on temporary tables seem to be involved every time. We store search results in dynamically generated temporary tables and the problematic operations create(d) MANY of them in recursive functions. We restored the test dbs from the same backup.
The servers (e.g. Windows v8.3.6 and Linux v8.3.5) don't crash though.
Remarkably older versions like v8.0.01.01 have been reported to now show this problem with the same db. I did check the psqlODBC's release notes but I have no idea which change could indirectly be resonsible.
I activated Mylog and Comlog in the system-DSN. The Uncompressed Mylog got pretty large (over 2,5 GB) so is there a way to change the standard paths for these logs?
It seems that Mylog uses quite a few resources as well - e.g. I had to increase max_locks_per_transaction considerably from normal. Otherwise our application would hang in transaction.
The compressed log-Files are still over 250 MB - so I didn't attach them.
Do I just have to increase other server/psqlODBC parameters to get rid of the crash?

Thank you very much in advance,

Peter
