[Lazarus] Error: Duplicate identifier "$ansistrrec18"

["Leonardo M. Ramé"]

Hi, I'm trying to build a CGI program using BrookFramework in FPC 3.1.1 
and Lazarus compiled today but I'm getting this error:

Error: Duplicate identifier "$ansistrrec18"

That identifier of course is not a variable, nor unit name, and it can't 
be found in any of the used files. Any hint?.

BTW, the error happens in a method of a Generic Class defined this way:

   generic TBaseGAction<T> = class(specialize TBrookGAction<T>)
   ...
   end;

Regards,
