Previous Comments: ------------------------------------------------------------------------ [2011-09-23 07:23:19] [email protected] I think you are wrong. zend_alloc works with pointers and size_t which have the same size as long on both 32-bit and 64-bit GCC. Also size of "long" and "long long" is the same on 64-bit GCC. ------------------------------------------------------------------------ [2011-09-22 16:46:59] [email protected] 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." Dmitry, can you review this? ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55764&edit=1
