Generally you are right.  However, people that encounter this bug most 
probably know little (if any) of the C++ Standard (and thus care little about 
conformance to the Standard), and people know well about the Standard most 
probably won't encounter this bug at all.  So I do not think this point really 
holds.

This is reasonable.  That was why I thought it was not necessary to `fix' this 
bug after some discussions.  I just thought it was still a bug, and some 
measures need to be taken to warn the user about this problem.  It might be of 
low priority, but simply marking it as `INVALID' just covers this problem.  
More people might discover this bug again and report it again, though they 
might not be as _____ (fill in adjectives that you like) as I am.
