Yes, 5.3.0's gmp works just fine with 5.3.1 (or any 5.3.x).
I did not see any relevent changes in 1.2.2 to do an update so late in
the 5.3.1 process, but I will update mpir to 1.2.2 next week. Snapshots
and the next release will have it. Move to "assigned" so I do not forget
this update :)
Thanks for your tests and feedbacks!

The problem is indeed lib_mipr. When I rebuilt php_gmp with mpir-1.2.0
(presumably the same version that was used for PHP 5.3.0) or with
mpir-1.2.2 (which was just released), the problem went away. The
release candidate of mpir-1.3.0 also yields an extension that runs
without crashing. I request/recommend that mpir-1.2.2 or higher be
included in PHP 5.3.2. The VC9 version of PHP runs fast enough on
Win32/PIII that the hardware is still useful. I can provide a PIII
compatible version of version of php_gmp for PHP 5.3.1 (using YASM and
based upon mpir-1.2.2) if anyone is interested. Also, php_gmp from
version PHP 5.3.0 *should* work with PHP 5.3.1.

The only difference between 5.3.0 and 5.3.1 is that we use ASM in
MPIR.
PIII is not on our tests matrix, niether it is on the MPIR one. I'll
try to create a C example and report this bug to the MPIR project. But
that's not a PHP bug per se (> bogus).

Description:
------------
Did the compiler options for GMP change between 5.3.0 and 5.3.1? The
code below executes properly in 5.3.0; but crashes when run using 5.3.1,
however, the stack traces (attached) are uninformative. Crash happens
as both an Apache2.2 module as well as CLI. Crash does NOT happen on
Core 2 Duo (Family 6, Model F, Stepping B), only on Pentium III
EB(Family 6, Model 8, Stepping 6). php_gmp on Windows usus MIPR which
supports x86 processors as old as the Pentium depending on how it was
compiled.
Reproduce code:
---------------
<?php
$a = '155172898181473697471232257763715539915724801'.
'966915404479707795314057629378541917580651227423'.
'698188993727816152646631438561595825688188889951'.
'272158842675419950341258706556549803580104870537'.
'681476726513255747040765857479291291572334510643'.
'245094715007229621094194349783925984760375594985'.
'848253359305585439638443';
$n = gmp_init($a, 10);
var_dump($n);
?>
Expected result:
----------------
resource(4) of type (GMP integer)
Actual result:
--------------
Apache 2.2 Backtrace
