Hi, am I missing something or is this a bug?
I'm trying to load a C++ DLL (a vst3). and most of it works perfectly, but i've got a case where the order of two mixins suddenly matters, but they mixin override functions.
looks like somehow the vtable gets screwed up.
code is minified to explain whats going on, i can provide a complete compilabe project if nessecary.
am i correct that this is a bug and the order of the two mixins shouldn't matter?
extern (C++)
class HostMessage : IMessage
{
public:
// somehow the order of the two mixins matters
mixin IMPLEMENT_REFCOUNT;
mixin QUERY_INTERFACE!(FUnknown, IMessage);
}
mixin template IMPLEMENT_REFCOUNT() {
override uint addRef() { return 1; }
override uint release() { return 1; }
}
mixin template QUERY_INTERFACE(Interfaces...) {
override tresult queryInterface (ref const TUID _iid, void** obj) { return 1; }
}
interface IMessage : FUnknown
{
public:
nothrow:
// @nogc:
/** Returns the message ID (for example "TextMessage"). */
FIDString getMessageID();
/** Sets a message ID (for example "TextMessage"). */
void setMessageID(FIDString id /*in*/);
/** Returns the attribute list associated to the message. */
IAttributeList getAttributes();
__gshared immutable TUID iid = INLINE_UID(0x936F033B, 0xC6C047DB, 0xBB0882F8, 0x13C1E613);
}
interface FUnknown : IUnknown {
__gshared immutable TUID iid = INLINE_UID(0x00000000, 0x00000000, 0xC0000000, 0x00000046);
}
interface IUnknown {
tresult queryInterface(ref const(TUID) _iid, void** obj);
uint addRef();
uint release();
}
