Please file a bug. It may also be that something is CFRetaining the
document that shouldn't be.

I've got a GC-only document-based application and I'm trying to add
basic print operations to my documents. I've reduced this down to
what I think is the absolute minimum required here and I'm still
seeing this bug.
With a completely new Document-based application I'm adding these 3
methods to my document class:
- (void)close {
NSLog(@"closing");
[super close];
}
- (void)finalize {
NSLog(@"finalizing");
[super finalize];
}
- (NSPrintOperation *)printOperationWithSettings:(NSDictionary *)
printSettings error:(NSError **)outError {
NSPrintInfo *printInfo = [self printInfo];
[printInfo setValuesForKeysWithDictionary:printSettings];
NSView *view = [[NSView alloc] initWithFrame:NSMakeRect(0, 0,
500, 500)];
return [NSPrintOperation printOperationWithView:view
printInfo:printInfo];
}
Now, if I run the program and open the print panel and cancel it a
few times in a row, usually 3 is enough and then close the document.
The document object itself will never finalize. And no documents
created or opened after that point will get finalized.
I've logged the document object address at creation time and once
I've seen that it has not been finalized I've paused the program and
tried info gc-roots and info gc-references on the document object.
gc-roots returns zero roots and gc-references returns nothing at all.
What am I missing?
