From: sixd Operating system: All PHP version: trunk-SVN-2011-09-22 (SVN) Package: Scripting Engine problem Bug Type: Bug Bug description:Review ZEND_MM_LONG_CONST on 64 bit
Description: ------------ Pointed out by Hannes on #php.pecl is a comment in http://pecl.php.net/bugs/bug.php?id=12821 by skatta72 at luukku dot com as follows: "I think I found this one. It's a missing L in Zend/zend_alloc.c: define ZEND_MM_LONG_CONST(x) (x##L) In 64bit system it should be define ZEND_MM_LONG_CONST(x) (x##LL) I found with gdb that the size - variable was way off where freeing a memory block and the resulting pointer caused the seg fault. Since that change, no crashes. This is inside the Zend memory management code. I wouldn't be surprised if it causes many other problems that occur randomly with php on 64-bit platform."
