Changing the declaration to
TB = class(TInterfacedObject, IA, IB) end;
workarounds the problem (Supports(TB, IA) returns true), but seems
strange in my opinion.
I haven't found any explanation for this e.g. in docs
(http://freepascal.org/docs-html/rtl/sysutils/supports.html ,
http://freepascal.org/docs-html/ref/refch7.html ).
Is this the expected behavior? Documented anywhere? Or is this a bug,
and I should submit it?
This is expected behavior. It works the same way as in delphi.
