The result of a SizeOf(Pointer) is know at compile time.
Does fpc optimize it and treat as a constant or will call the SizeOf

Thanks in advance.

Take the following example:
for i:= 0 to 2 do;
WriteLn(i);
Can i safely assume that after the for loop the value of "i" is 2?
Thanks in advance

No, it can be anything, and the actual value even depends on the
compiler version
The Pixel editor, which is compiled with fpc AFAIK, is available to Zeta
OS.
Does fpc runs in Zeta? (Or maybe he is using another compiler?)
Someone has info about this?

I'm tracing a memory leak in a Delphi ported component and found that
the culprit was a TInterfacedObject descendant that was not being freed.
I found that if i directly call Free or _Release the memory leak
vanishes (Delphi code does not call these).
My question is: is TInterfacedObject des

or other implemented interface
Thanks. You are right. Using Manager as IDropSource there's no leak in
the test program.
Unfortunately in the original code Manager is already an interfa

If you have two or more interfaces whose members point each other in a

It can work for that case, but I think that is not a good ideia.

This was my first idea. And now gains force again. The problem is
that the bug can not be isolated easily.
Another option is that there's a mem leak in delphi also. Does some
one know how to trace a mem leak in delphi?
Use FastMM with FullDebugOptions

I'm trying to declare a standalone function (not attached to a class) to
use as a TNotifyEvent.
I tried
procedure FooBar of object;
begin
end;
Without sucess.
Is it possible to declare such function to use as a TNotifyEvent without
creating a class only to hold the callback method?

It seams that semaphores would be a good solution. I took a look at
