[Bug 503396] Re: canary mismatch on efree()

I have not been able to reproduce this problem outside of the current
production environment. And I can't realistically try to run php under
valgrind since these are paying clients, and I can't risk their sites
stability, etc.

The other problem with reproducing this is that it takes some time to
manifest. Its related to the form submissions on the site. On any given
day there probably are 25-50 form submissions (some are very large
multi-page forms too), and it takes maybe a week or so of this, for the
error to start showing up. I don't really know a way to duplicate all
that in a controlled environment. My guess is that if I restart apache
every day, I'd never see the error at all.

I do have a copy of the site in a staging environment. I have never seen
the error there, but there is really no traffic to speak of.
