This is precisely the warning I've been getting, I've been embedding
Python 2.6 in an application built using g++ 4.4.

Thanks, I'll add my 2c worth on those issues.
Even if it is eventually decided not to backport those patches to 2.7,
it would be nice if the documentation could be updated to indicate
that strings passed to those functions won't be modified, so that API
users like myself can feel a little safer when passing literals in,
without having to trawl through the interpreter source to see if the
arguments are modified.
Thanks,
