#49597 [Opn->Fbk]: sprintf('%s',join('',array(false))); crashes

ID: 49597 Updated by: jani@php.net Reported By: markgdesign at gmail dot com -Status: Open +Status: Feedback Bug Type: Reproducible crash Operating System: Windows Vista Home PHP Version: 5.2.11 New Comment: Please try using this snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://windows.php.net/snapshots/ I can not reproduce this. Previous Comments: ------------------------------------------------------------------------ [2009-09-19 02:36:35] markgdesign at gmail dot com Description: ------------ An array with a false or null element, joined, then used in sprintf apparently causes PHP to crash. Actually, Apache cycles endlessly making the OS think it has crashed. This is the simplest expression I can create which causes the problem: sprintf('%s',join('',array(false))); Forcing the result of join into type string avoids the problem: sprintf('%s',(string) join('',array(false))); Reproduce code: --------------- sprintf('%s',join('',array(false))); Expected result: ---------------- I expected it to join all array elements (interpreting false and null values as empty strings) and pass it to sprintf. Actual result: -------------- Apache cycled without responding to the page request. The Windows OS interpreted this as a crash, although Apache did not actually stop working or need to be restarted. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=49597&edit=1
