Because the packet might not be malformed; it might just be that the 
*dissector* is malformed.
Insead, the checks (which should be done in *all* versions, even 
production versions) should probably throw a new exception, which
	1) causes something such as "[Dissector bug]", perhaps with an 
assertion string containing the file/line and assertion expression, as 
well as the protocol name, so we know what protocol was being dissected;
	2) call "report_failure()", so that a dialog box is popped up in 
Ethereal and a message is printed in Tethereal, so that the user knows 
that there's something wrong and is thus more likely to tell us about it.
