#48247 [NEW]: PHP crashes on errors during startup

From: dmitry@php.net Operating system: * PHP version: 5.3CVS-2009-05-12 (CVS) PHP Bug Type: Date/time related Bug description: PHP crashes on errors during startup Description: ------------ PHP crashes in case of warning messages during MINIT(). In case of warning messages during MINIT() the php_log_err() function is called. In case error_log directive is set to log errors into file this function tries to add timestamp using formatting through php_format_date(). However it leads PHP into infinity recursion if TZ isn't set, because php_format_date() throws another warning. Even preventing the recursion with static flag makes PHP crash in ext/date because of uninitialized DATEG(tzcache). #0 0x084922d2 in zend_hash_find (ht=0x89e9ac8, arKey=0x857edbd "Europe/Moscow", nKeyLength=14, pData=0xffffceac) at /home/dmitry/php/php5.3/Zend/zend_hash.c:880 #1 0x08142ff1 in php_date_parse_tzfile ( formal_tzname=0x857edbd "Europe/Moscow", tzdb=0x85cb9c8) at /home/dmitry/php/php5.3/ext/date/php_date.c:813 #2 0x081432a9 in get_timezone_info () at /home/dmitry/php/php5.3/ext/date/php_date.c:917 #3 0x08144d8c in php_format_date (format=0x899b203 "d-M-Y H:i:s", format_len=11, ts=1242143549, localtime=1) at /home/dmitry/php/php5.3/ext/date/php_date.c:1166 #4 0x08415f16 in php_log_err ( log_message=0xf7f8f678 "PHP Warning: test in Unknown on line 0") at /home/dmitry/php/php5.3/main/main.c:547 #5 0x08416db9 in php_error_cb (type=2, error_filename=0x89b00cf "Unknown", error_lineno=0, format=0x899bb97 "test", args=0xffffd088 "\005") at /home/dmitry/php/php5.3/main/main.c:958 #6 0x084832d2 in zend_error (type=2, format=0x899bb97 "test") at /home/dmitry/php/php5.3/Zend/zend.c:1020 #7 0x08418ecf in php_module_startup (sf=0x89d11a0, additional_modules=0x0, num_additional_modules=0) at /home/dmitry/php/php5.3/main/main.c:2021 #8 0x08546f59 in php_cli_startup (sapi_module=0x89d11a0) at /home/dmitry/php/php5.3/sapi/cli/php_cli.c:399 -- Edit bug report at http://bugs.php.net/?id=48247&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48247&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48247&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48247&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48247&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48247&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48247&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48247&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48247&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48247&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48247&r=support Expected behavior: http://bugs.php.net/fix.php?id=48247&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48247&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48247&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48247&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48247&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48247&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48247&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48247&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48247&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48247&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48247&r=mysqlcfg
