From: alan@akbkhome.com Operating system: linux debian PHP version: 4.3.0 PHP Bug Type: Reproducible crash Bug description: GTK: possible memory leak in ctree insert_node code. PHP-GTK 0.5.1 (I dont think anything major changed in this area on 0.5.2????) to reproduce try pear install http://devel.akbkhome.com/GTK_VarDump-0.1.tgz the package includes a test file test1.php, just run it with php test1.php it attempts to var_dump globals (dont worry recursion is handled..)... try expanding the globals recursive element a few times, then press the OK button - I get the following segfault... if somebody can reproduce it, it would atleast prove im not mad here :) I tested this on another machine, which had the zend memory lead debugging on (and an earlier dev version of PHP4.3), indicating there was a 4 byte leak in in gtk+.overides in the gtk_ctree_insert_node section at this line.. text = emalloc(sizeof(gchar *) * columns); however couldnt get it to crash :( (gdb) run /usr/share/pear/tests/GTK_VarDump/tests/test1.php Starting program: /usr/bin/php /usr/share/pear/tests/GTK_VarDump/tests/test1.php Program received signal SIGSEGV, Segmentation fault. 0x402a8e5a in free () from /lib/libc.so.6 (gdb) bt #0 0x402a8e5a in free () from /lib/libc.so.6 #1 0x08129ad9 in _efree (ptr=0x8520cf4) at /usr/src/php/php-4.3.0/Zend/zend_alloc.c:235 #2 0x0813d360 in zend_hash_apply_deleter (ht=0x81b5460, p=0x8520cf4) at /usr/src/php/php-4.3.0/Zend/zend_hash.c:633 #3 0x0813d51b in zend_hash_apply_with_argument (ht=0x81b5460, apply_func=0x813e644 <clean_module_resource>, argument=0x8476270) at /usr/src/php/php-4.3.0/Zend/zend_hash.c:708 #4 0x0813e6a8 in zend_clean_module_rsrc_dtors_cb (ld=0x8476258, module_number=0xbffff320) at /usr/src/php/php-4.3.0/Zend/zend_list.c:249 #5 0x0813d50a in zend_hash_apply_with_argument (ht=0x81b1080, apply_func=0x813e660 <zend_clean_module_rsrc_dtors_cb>, argument=0xbffff320) at /usr/src/php/php-4.3.0/Zend/zend_hash.c:707 #6 0x0813e6f5 in zend_clean_module_rsrc_dtors (module_number=28) at /usr/src/php/php-4.3.0/Zend/zend_list.c:260 #7 0x0813b6b0 in module_destructor (module=0x823e5f0) at /usr/src/php/php-4.3.0/Zend/zend_API.c:1117 #8 0x0813d2ac in zend_hash_apply_deleter (ht=0x81b5600, p=0x823e5c0) at /usr/src/php/php-4.3.0/Zend/zend_hash.c:598 #9 0x0813d493 in zend_hash_apply (ht=0x81b5600, apply_func=0x813b78c <module_registry_cleanup>) at /usr/src/php/php-4.3.0/Zend/zend_hash.c:689 #10 0x08138a40 in zend_deactivate_modules () at /usr/src/php/php-4.3.0/Zend/zend.c:634 #11 0x0810fdcd in php_request_shutdown (dummy=0x0) at /usr/src/php/php-4.3.0/main/main.c:928 #12 0x0815267d in main (argc=2, argv=0xbffffa94) at /usr/src/php/php-4.3.0/sapi/cli/php_cli.c:803 (gdb) -- Edit bug report at http://bugs.php.net/?id=21538&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=21538&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=21538&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=21538&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=21538&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=21538&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=21538&r=support Expected behavior: http://bugs.php.net/fix.php?id=21538&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=21538&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=21538&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=21538&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=21538&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=21538&r=dst IIS Stability: http://bugs.php.net/fix.php?id=21538&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=21538&r=gnused
