Thank you for the report, and for helping us make PHP better.

Dmitry, you maybe want to review this fix. thanks :)

dmitry, I have a quick look at this, since due to cache mechanism, I have not
gat familiar with this area.
it is better if you can have a look at this. I will keep troubleshooting anyway
:).
