It shouldn't.  C99 explicitly has this as an example (6.7.8.32).  It's also of 
note that
  char *p = "abc"
is different from
  char a[] = "abc"
in that the elements of a are modifiable, while modifying p[x] yields 
undefined behavior.

But this is increasingly getting out of scope for hackers@ ... so I'll shut up 
now.
