[DUG] Memory leak - can't find

[Myles Penlington]

Not really a leak. It's an object created in a unit initialization, but the unit has not been finalized by the time the leak reporting has been done.

If you put a break point on SyncObjs][TCriticalSection.Create] you will find the unit responsible - prob in system/sysutils/sysinit/,
Best to log it as a leak to be ignored.

Myles.

Subject: [DUG] Memory leak - can't find

Hi there,

Just enabled memory reporting and got one that I just can't track down.
I open my app, and close it and it occurs. I added the full FastMM and 
enabled 'INclude TD32 debug info' and it doesn't really help much.

I have checked the onCreate of my main form and my application source - 
tired commenting it all out (except Application.CreateForm(TfMain, 
fMain); and still doesn't help.

This is my log dump.

This application has leaked memory. The small block leaks are (excluding 
expected leaks registered by pointer):

21 - 28 bytes: TCriticalSection x 1

Note: Memory leak detail is logged to a text file in the same folder as 
this application. To disable this memory leak check, undefine 
"EnableMemoryLeakReporting".
