That is not what the part  of the standard I quoted says.  It very
clearly forbids the sorting function from depending on the pointers'
values.  I can even see an implementation actually using this
requirement.

And it is well known that some qsort implementations will do nasty
things if the sorting order is not consistent.  I've seen Perl core
dumps on that account, although that is a while ago.
