Memory Errory detected by FastMM in DirectMode

Posted: Fri 19 Jul 2013 11:39

Hello,

FastMM detects a memory error in the new ODAC Version 9.0.2.
It occurs in DirectMode with String-Parameter Assignemt (GetMaxStringSize call).
I can provide a test application if needed.

Could you fix it, please.

Kind regards,


Bernd

please send fixed version for XE2 to me (Bernd and me are working together).
When you will release next official build?

BTW: With current version I am getting compilation error when trying to build UniDac.
This is the log:

Hello,

Most probably, you have old *.bpl, *.dcu, *.pas, etc., files remained. Please delete all the old files and try reinstalling UniDAC once more.
