#36477 [NEW]: Exceptions break debug_backtrace()

From: ch at westend dot com Operating system: Linux PHP version: 5.1.2 PHP Bug Type: Scripting Engine problem Bug description: Exceptions break debug_backtrace() Description: ------------ After calling "throw new Exception(..)" and entering the function registered with "set_exception_handler()" the debug_backtrace() output is empty. This is very inconvinient for self written error handling functions as "trigger_error()" for example works fine for debug_backtrace. I'm aware that the exception itself contains a stack trace but is there really a reason to empty debug_backtrace()? Reproduce code: --------------- <?php function exception_handler($e) { debug_print_backtrace(); } function c() { throw new Exception("Problem!"); } function b() { c(); } function a() { b(); } set_exception_handler('exception_handler'); a(); ?> Expected result: ---------------- Backtrace with #1 exception_handler from c() #2 c() from b() #3 b() from a() #4 a() from main Actual result: -------------- #0 exception_handler(Exception Object ([] => Problem!,[] => ,[] => 0,[] => /home/ch/tt.php,[] => 5,[] => Array ([0] => Array ([file] => /home/ch/tt.php,[line] => 6,[function] => c,[args] => Array ()),[1] => Array ([file] => /home/ch/tt.php,[line] => 7,[function] => b,[args] => Array ()),[2] => Array ([file] => /home/ch/tt.php,[line] => 10,[function] => a,[args] => Array ())))) called at [(null):0] -- Edit bug report at http://bugs.php.net/?id=36477&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=36477&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=36477&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=36477&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=36477&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=36477&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=36477&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=36477&r=needscript Try newer version: http://bugs.php.net/fix.php?id=36477&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=36477&r=support Expected behavior: http://bugs.php.net/fix.php?id=36477&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=36477&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=36477&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=36477&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=36477&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=36477&r=dst IIS Stability: http://bugs.php.net/fix.php?id=36477&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=36477&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=36477&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=36477&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=36477&r=mysqlcfg
