Today a colleague of mine was trying to import VMWare 5.5 WSDL into Delphi. When he tried to compile the application, it got:
[DCC Error] vimService.pas(60427): E2575 RTTI for 'VimPortType' is too large; reduce scope with $RTTI or
reduce type size
Delphi Doc Wiki says (XE7 too):
This occurs when the generated RTTI is too large (greater than 64kB).
