[DUG] FastMM4 memory leak report

Third time lucky and I guess I need a good cup of coffee. So, one more time with style :0)


Yes, they are known bugs in the VCL.

See links:

The later proposes a work around and notes that it was meant to have been fixed in SP2.

Cheers,
Darrell.

Subject: [DUG] FastMM4 memory leak report

Hi guys - I'm getting a small memory leak report which I'm not sure that 
I can do anything about. I'm running Delphi 6 with SP4. The report has a 
couple of entries like the one below.
Is this a known bug in the Delphi VCL?

Cheers,
Phil.
