#30 strange memory leak detection

[Anonymous]

FastMM reports a strage memory leak...

4DCFCC [Params\optParams.pas][optParams][ToptParam.Create][634]
where this line numer 634 is very simple: _GroupName := S_NONE;

where _GroupName is a protected string field of class ToptParam
_GroupName: string;

what it could be?

here a full dump:
