I guess it's because of this:

Changed paths:
    M /trunk/compiler/ncgrtti.pas
    M /trunk/compiler/pdecsub.pas
    M /trunk/compiler/symconst.pas

   * removed any use of pushleftright_pocalls for non-i386 platforms,  
since
     they always use the same parameter pushing order
   * define the pushleftright_pocalls constant only for i386 so it  
cannot
     be accidentally used anymore for other platforms

The parameter order was simply wrong in the rtti for x86_64, afaik.  
For i386, the parameter order depends on the used calling convention  
(and this was used correctly for the rtti), but other architectures it  
does not (while the rtti claimed otherwise).
