Referencing NULL pointers

[Tom Neff]

I would also point out:

 (1) A truly portable application is unlikely to have any legitimate need
	 to mess with things at "real" address 0.  Lots of system-y type programs
	 might have an excuse (it's a manipulable interrupt vector location in
	 the Intel architectures for instance) but by definition they are not
	 very portable.

 (2) In architectures where accessing address 0 is a legitimate concern,
	 good compilers will probably provide a non-ANSI non-portable extension
	 of some kind to let you do it.  The pANS is not a nursemaid.
