-Status: Open
+Status: Bogus
Bug Type: Reproducible crash
Operating System: Windows XP XP3
PHP Version: 5.3.1
New Comment:
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
