I found a fix on Zend's repository,
http://svn.php.net/viewvc/php/php-src/trunk/Zend/zend_strtod.c?r1=307095&r2=307094&pathrev=307095

Does anyone know anything about what caused this bug, how come a "volatile"
fixed it (what, it was a gcc optimization bug?), and what does it have to do
with 32 vs 64 bits?
