Miguel, I do not think this is Delphi or mysql.pas related at all... It's just repeated calls to fetch and should be checked in plain C. Probably duplicate of that bug verified by Sveta.

I agree that it is probably neither Delphi or MySQL.pas related. The is still there using Lazarus/FPC and MySQL50dyn.pas, as described earlier. I am really hoping that there is a way to work around this. It seems like a very fundamental part of the API that is broken. How does everyone else use MySQL then ?

Thank you for the report. If you think this is same as bug #45002 why do you open new one? What is the difference?

Well actually I have never seen valgrind output before and I dont read C code well. Forgive me my ignorance in these fields I thought the bug might be related, but I am not sure. I have located the bug to the MySQL_Free_Result function, which sometimes does free allocated memory by MySQL_Store_Result, and sometimes not. I thought this info might help fixing the bug.

Thank you for the feedback. I can not repeat described behavior with C test case. Please send us complete Delphi project so we can try it.
