Dmitry,
From your explanation it sounds like there should be any issues with
putting this patch into the next 5.2.X release.

The core_globals structure is allocated/initialized in PHP itself

No one extension does it.
Thanks. Dmitry.

If there really is no reason for an extension to use this,
then I am
ok with it. I was thinking an extension might be defining a stream
and setting this.
i think the problematic scenario would be an extension that
was previously
compiled with (and allocated/initialized an instance of) the
old smaller
struct, which then passed said struct to a function from the
newer core
version, which would expect that it was a the new (larger)
struct, and
attempt to access memory outside the bound of the older struct.
but i'm not familiar enough with the code in question to know
how this struct
used and passed around between extensions and the core.
