>Description:
Application that uses MyODBC 3.51.05 + MySQL 4.0.10
constantly grow memory consumption. Such behavior is not
observed if MyODBC 3.51.05 + MySQL 3.23.55 are used. I suppose
that there is memory leakage in libmysqlclient. Application
linked directly with libmyodbc3 (instead ODBC manager). All
internal memory allocations are controlled by special
routines. So my own application remain above suspicion.
>How-To-Repeat:
Standard procedure (taken from ODBC manual) to make SQL
request.
>Fix:
Downgrade to MySQL 3.23.55
