Does it matter exactly where the bug is? It breaks compilation on arm and sparc
as far as I can tell, and the patch is really simple. The problem is not caused
by aggressive optimisations at least. I would not bother upstream with it if it
was.

This is not a PHP problem. The C code is absolutely legal and wrong compilation
caused by a bug in GCC or too aggressive optimization options that make wrong
assumptions.

The Gentoo patchset has been running with this for years now. Any reason why
this
has not been resolved yet?

There are Gentoo downstream bugs related to this issue:

I'd love to see this fixed upstream, but will ship a custom patch to get this
more testing shortly.

Dmitry, can you check this?

To clarify... the Zend code reads via zval *, not long *. The cut down test
case I submitted was simplified to use a long *.
