Hi David,

I made a patch for a similar issue here:
https://bugs.php.net/bug.php?id=63615

I wonder if this would fix your issue as well.

I pulled it as a random bug fix, but did note that there is some
discrepancy on whether this is intended behavior or not. I'm with Stas
that we should either fix it and make it consistent, or document why
it isn't.
