FastMM Memory Error Detected beim Debuggen

[TiGü]

Ich zweifle langsam an mir?!
Entweder FastMM hat nen schweren Bug oder die VCL-Sourcen haben nen Sprung.

Beispielprogramm OHNE DLL Beteiligung im Anhang (mit FastMM_FullDebug.dll).

Delphi-Quellcode:

procedure TMainForm.Test;
var
 str : string;
begin
  str :=  edt1.Text;
  lbl1.Caption := str;
end;

Wenn ich hier reindebugge und per MouseOver mir die Werte für edt1.Text und für lbl1.Caption im Debug-Hint anzeigen lasse, bekomme ich beim Beenden einen Memory Leak Report für 2 x UnicodeStrings:

Code:

--------------------------------2012/8/10 16:15:27--------------------------------
A memory block has been leaked. The size is: 68

This block was allocated by thread 0x12E4, and the stack trace (return addresses) at the time was:

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

The allocation number is: 650

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

53 - 68 bytes: UnicodeString x 2

Note: This memory leak check is only performed if Delphi is currently running on the same computer. Memory leak detail is logged to a text file in the same folder as this application. To disable this memory leak check, undefine "EnableMemoryLeakReporting".
