#21478 [Ver]: Zend/zend_alloc.c :: shutdown_memory_manager produces segfault

ID: 21478 Updated by: sniper@php.net Reported By: pollita@php.net Status: Verified Bug Type: Scripting Engine problem Operating System: linux PHP Version: 4CVS-2003-01-06 (dev) New Comment: I don't know what this 4.5-dev is..since the only official development branches are PHP_4_3 and the php5 module. Try this snapshot: http://snaps.php.net/php4-STABLE-200303192030.tar.gz If that doesn't work, but the RC1 works, then it's a problem with the build tools on the snaps.php.net machine. (Please send me that test script you used when testing 4.3.2-RC1) Previous Comments: ------------------------------------------------------------------------ [2003-03-19 15:18:36] black@php.net sniper, yes, i wasn't able to reproduce it on php4.3.2rc1 i did have one segfault it normal operation mode (not inside gdb), but i couldnt reproduce it in any way or form similar to the process of reproducing on the latest -STABLE or 4.5-dev snapshots as far as i can tell 4.3-dev and 4.5-dev are subject to this.. im not even going to guess what goes on in 5.0-dev yet.. btw, there is a slight difference between the backtrace ilia got above and mine, so it might be an unrelated problem... still the same scope and behaviour thou. ------------------------------------------------------------------------ [2003-03-18 20:08:32] sniper@php.net [To: black@php.net] Did I understand correctly that you can't reproduce this with 4.3.2RC1, but you CAN reproduce it with the latest stable snapshot?? This might mean that some tools on the machine generating the snapshots are bad versions.. (the RC1 source package was generated on my machine :) ------------------------------------------------------------------------ [2003-03-18 13:45:09] black@php.net ok, i cant reproduce the behaviour on my part on as low as php-4.3.2RC1 (this one works flawlessly, as far as i can tell). ------------------------------------------------------------------------ [2003-03-18 12:42:44] black@php.net seems to be identical on the last 4.3-STABLE snapshot from ~20 minutes ago, i guess its the same on 4.5 i will try to track down the 4.3.1 source version and try if it crashes there too, i kinda hope it doesn't. ------------------------------------------------------------------------ [2003-03-18 11:34:19] black@php.net (gdb) frame 0 #0 _zval_ptr_dtor (zval_ptr=0x0) at /root/src/php4-standard/Zend/zend_execute_API.c:289 289 (*zval_ptr)->refcount--; (gdb) frame 1 #1 0x4036240c in zend_hash_destroy (ht=0x814131c) at /root/src/php4-standard/Zend/zend_hash.c:543 543 ht->pDestructor(q->pData); maybe checking zval_ptr for null would be a nice idea? (this is another bt, same output just the final pointer is 0x0) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
