Memory Leak on ZUpdateSQL

[lams]

Hi,

I am using ZeosLib 6.6.4, D6 and Firebird 2.1 with latest http://sourceforge.net/projects/fastmm/ ... MM4%204.90

And the FastMM4 fulldebugmode report hugh memory leak on ZeosLib components. I have write a very simple test app using Firebird 2.1 default Employee sample database as test case and get the same memory leak result.

I have attach the test project and my FastMM FastMM4Options.inc which include the debug mode settings.

Here is some snip from the FastMM debug log:

Code: Select all

A memory block has been leaked. The size is: 20

This block was allocated by thread 0xD78, and the stack trace (return addresses) at the time was:

The block is currently used for an object of class: Unknown

The allocation number is: 8007
