Dear developer, how specific of you... I expect a scripting language such as php to trap a stack overflow or whatever I can throw at it.

PHP 4.3.3 (cli) (built: Sep 17 2003 22:54:17) Copyright (c) 1997-2003 The PHP Group Zend Engine v1.3.0, Copyright (c) 1998-2003 Zend Technologies with Zend Optimizer v2.1.0, Copyright (c) 1998-2003, by Zend Technologies Reproduce code: --------------- <?php function debug ($text='', $level=2, $file='', $line=0) { if (is_writable ('/logs/error.log')) { error_log ("$debug_string\n", 3, '/logs/error.log'); } else { debug ('Error Log Not Writable', 2); } } debug ('Test'); ?> Expected result: ---------------- I expect an out of memory error or something to be caught. Instead it seems the engine gets caught in an infinite loop like my code and dies painfully. Actual result: -------------- 0x28ade8cb in zend_assign_to_variable_reference () from /usr/local/libexec/apache/ZendOptimizer.so Or! If I add a call to error_log to count function calls (in my case it was 8976 before engine crashed)... then I get... 0x81a07c1 in zend_hash_quick_add_or_update () from /usr/local/libexec/apache/ZendOptimizer.so If I remove zend_optimzer.so from php.ini I get this error 0x819aa2e in zendi_smart_strcmp () Backtrace is thousands and thousands of any of the given above messages. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26306&edit=1
