The current implementation relies on undefined behavior and apparently
the overflow check can be optimized away.

Reopening it because somebody with commit access to the engine needs to
apply and commit the patch there. The other patch can be found at
http://git.debian.org/?p=pkg-php/php.git;a=blob;f=debian/patches/zend_int_overflow.patch;hb=0fe497525d46b2fa8353e37106b47c05ef804cc5

Duplicate.

Indeed. I just checked with the -O0 build and it passes.

The affected code in this case is ZEND_HANDLE_NUMERIC in
Zend/zend_hash.h

Should this one be assigned to somebody in particular?

Possibly same issue as bug #51023 ??

It fails for me with 5.3.1 on i686, ia64, s390, alpha, powerpc, x86_64,
etc. Even on those running kfreebsd.
It also fails with the latest 5.3 svn on ia64 (haven't built it on any
other arch.)
