Summary:  - cellFrameForText... in NSTextAttachmentCell is called recursively

Original Submission:  If a subclass of NSTextAttachmentCell returns
-cellFrameForTextContainer:proposedLineFragment:glyphPosition:characterIndex:
with a height of NSRect which is exactly the same as the height of the 
proposedLineFragment,
this method will be called recursively and the height of proposedLineFragment 
keep increasing.

An example looks like this:

- (NSRect) cellFrameForTextContainer: (NSTextContainer *)c
                proposedLineFragment: (NSRect) lf
                glyphPosition: (NSPoint) p
                characterIndex: (unsigned int) ci
{
  return NSMakeRect(0, 0, lf.size.width-10, lf.size.height);
}

It can be verified in HelpViewer.app by changing the return NSRect in HRCell.m
