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.
