Please check the latest git version. The following commit might fix the problem. http://git.php.net/?p=php-src.git;a=commitdiff;h=aa3fd8c849dc9d05ff1dcd9e21ca63b69cda8f61 ------------------------------------------------------------------------ [2015-09-07 20:20:20] pegasus at vaultwiki dot org After a few days, issue persists using the suggested commit (different line numbers): ### #0 0x000000000094733b in zend_mm_find_leaks_small (p=0x7f7df2200000, i=510, j=6, leak=0x7fffbe955cf0) at /home/***/php-src-0f74bae/Zend/zend_alloc.c:1966 1966 if (dbg->size != 0) { ### p dbg $1 = (zend_mm_debug_info *) 0x7f7df24002e0 p bin_num $2 = 24 p dbg->size Cannot access memory at address 0x7f7df24002e0 p leak->filename $3 = 0xfe5540 "/home/***/php-src-0f74bae/Zend/zend_vm_execute.h" p leak->lineno $4 = 15242 I have not checked exhaustively, but when comparing to other instances of the error, it seems bin_num = 24 is a pattern here (and dbg->size is always inaccessible). ------------------------------------------------------------------------ [2015-09-02 12:16:57] pegasus at vaultwiki dot org I will try the new commit and watch the logs for a few days to see if the error still occurs. I will also work on getting you the output of those variables next time I am at the terminal. ------------------------------------------------------------------------ [2015-09-02 10:09:18] dmitry@php.net Please check the latest git version.
