"#1 0xb739e2f2 in xdebug_execute (op_array=0x9ce5214) at /tmp/pear/temp/xdebug/xdebug.c:1392" I tried it on a non-xdebug php 5.2.10, and that had no problems - the 5.3.1 I tested with did not have xdebug installed either. Will throw the bug that way then.. apologies for the misdirected bug report! ------------------------------------------------------------------------ [2010-05-14 15:04:40] daan at react dot com JIC you still need it - a trace: #0 0x0837f473 in zend_hash_find (ht=0x9ce0398, arKey=0xb73babed "", nKeyLength=5, pData=0xbfc0ea7c) at /usr/src/php-5.2.13/Zend/zend_hash.c:880 #1 0xb739e2f2 in xdebug_execute (op_array=0x9ce5214) at /tmp/pear/temp/xdebug/xdebug.c:1392 #2 0x08368c20 in zend_call_function (fci=0xbfc0ebec, fci_cache=0xbfc0ec10) at /usr/src/php-5.2.13/Zend/zend_execute_API.c:1039 #3 0x08387b2c in zend_call_method (object_pp=0xbfc0ec94, obj_ce=0x9ce3c0c, fn_proxy=0xbfc0ec98, function_name=0x8638cb8 "__destruct", function_name_len=10, retval_ptr_ptr=0x0, param_count=0, arg1=0x0, arg2=0x0) at /usr/src/php-5.2.13/Zend/zend_interfaces.c:88 #4 0x0838da67 in zend_objects_destroy_object (object=0x9ce4898, handle=1) at /usr/src/php-5.2.13/Zend/zend_objects.c:101 #5 0x08390d30 in zend_objects_store_del_ref_by_handle (handle=1) at /usr/src/php-5.2.13/Zend/zend_objects_API.c:198 #6 0x08390d75 in zend_objects_store_del_ref (zobject=0x9ce22c4) at /usr/src/php-5.2.13/Zend/zend_objects_API.c:169 #7 0x08367ee9 in _zval_ptr_dtor (zval_ptr=0x9ce4928) at /usr/src/php-5.2.13/Zend/zend_variables.h:35 #8 0x0837e245 in zend_hash_destroy (ht=0x9ce48ec) at /usr/src/php-5.2.13/Zend/zend_hash.c:526 #9 0x0838dc07 in zend_object_std_dtor (object=0x9ce3284) at /usr/src/php-5.2.13/Zend/zend_objects.c:45 #10 0x0838dc40 in zend_objects_free_object_storage (object=0x9ce3284) at /usr/src/php-5.2.13/Zend/zend_objects.c:122 #11 0x08390d52 in zend_objects_store_del_ref_by_handle (handle=2) at /usr/src/php-5.2.13/Zend/zend_objects_API.c:211 #12 0x08390d75 in zend_objects_store_del_ref (zobject=0x9ce48d4) at /usr/src/php-5.2.13/Zend/zend_objects_API.c:169 #13 0x08367ee9 in _zval_ptr_dtor (zval_ptr=0x9ce46f8) at /usr/src/php-5.2.13/Zend/zend_variables.h:35 #14 0x0837e245 in zend_hash_destroy (ht=0x9ce4548) at /usr/src/php-5.2.13/Zend/zend_hash.c:526 #15 0x0836c123 in destroy_zend_class (pce=0x9d1a78c) at /usr/src/php-5.2.13/Zend/zend_opcode.c:184 #16 0x0837de9c in zend_hash_apply_deleter (ht=0x9b136a0, p=0x9d1a780) at /usr/src/php-5.2.13/Zend/zend_hash.c:611 #17 0x0837dfcb in zend_hash_reverse_apply (ht=0x9b136a0, apply_func=0x83675b0 <clean_non_persistent_class>) at /usr/src/php-5.2.13/Zend/zend_hash.c:760 #18 0x0836a8b6 in shutdown_executor () at /usr/src/php-5.2.13/Zend/zend_execute_API.c:291 #19 0x083752e4 in zend_deactivate () at /usr/src/php-5.2.13/Zend/zend.c:860 #20 0x083356eb in php_request_shutdown (dummy=0x0) at /usr/src/php-5.2.13/main/main.c:1504 #21 0x083e0872 in main (argc=2, argv=0xbfc0f4f4) at /usr/src/php-5.2.13/sapi/cli/php_cli.c:1346 ------------------------------------------------------------------------ [2010-05-14 15:00:16] fel...@php.net In fact I got something on Valgring log: Invalid write & read and: ==5285== Address 0x65f0ba4 is 4 bytes inside a block of size 256 free'd ==5285== at 0x4024866: free (vg_replace_malloc.c:325) ==5285== by 0x83ACBD6: _efree (zend_alloc.c:2308) ==5285== by 0x83CD787: zend_ptr_stack_destroy (zend_ptr_stack.c:74) ==5285== by 0x83BE48B: shutdown_executor (zend_execute_API.c:283) ==5285== by 0x83D05D9: zend_deactivate (zend.c:860) ==5285== by 0x836D12B: php_request_shutdown (main.c:1504) ==5285== by 0x8459950: main (php_cli.c:1346) ------------------------------------------------------------------------ [2010-05-14 14:58:06] fel...@php.net Please try using this snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://windows.php.net/snapshots/ I cannot reproduce it on 5_2 SVN. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
