No.

That's the same I used for testing this.

So, I suppose, you're still using libc from Squeeze, right?

Well, I suppose that it would not work either way if that was the
problem ;-)

Right. I suppose PHP uses the glob(3) function from libc, so you're
"mixed" setup might cause that problem. I fully agree that this should
be fixed, but the question is if this bug is to be considered RC.
Anyway, since the patch is fairly trivial, I'll try to get it into
Wheezy -- after all, there might be other architectures / setups that
would cause this problem as well.

Cheers,
Sebastian
