#48816 [Opn->Asn]: IteratorIterator seek() causes bus error

ID: 48816 Updated by: pajoye@php.net Reported By: kim at burgestrand dot se -Status: Open +Status: Assigned Bug Type: SPL related Operating System: Mac OS 10.5.7 PHP Version: 5.3.0 -Assigned To: +Assigned To: colder Previous Comments: ------------------------------------------------------------------------ [2009-07-06 15:56:27] kim at burgestrand dot se I compiled PHP 5.2.10 (configure command: './configure' '--with-mysql=/usr/local/mysql' '--with-mysqli=/usr/local/mysql/bin/mysql_config' '--enable-mbstring' '--with-curl=/usr' '--enable-sockets' '--with-libxml-dir=/opt/local/include/libxml2/libxml' '--with-pdo-mysql=shared,/usr/local/mysql' '--with-iconv=shared,/opt/local' '--with-apxs2' '--with-config-file-path=/etc/php' '--with-config-file-scan-dir=/etc/php/conf.d') and tested the code. No out of bounds exceptions, and the output was consistent: “int(0) int(1)” ------------------------------------------------------------------------ [2009-07-06 15:51:24] kim at burgestrand dot se I had the same issue on Debian using PHP 5.2.6-3 with Suhosin-Patch 0.9.6.2… sometimes. I mean, have a peek at this output: http://pastebin.com/f1dd1bc27 (linked to pastebin because the bug system thinks I'm spamming) Same code as submitted, with a shebang added to the top “#!/usr/bin/env php”. ------------------------------------------------------------------------ [2009-07-06 13:46:34] pajoye@php.net I can't reproduce here, I got a out of bounds exception on the seek call. ------------------------------------------------------------------------ [2009-07-06 13:32:52] kim at burgestrand dot se Description: ------------ After using seek() on an IteratorIterator containing an ArrayIterator the next() call results in a bus error. Also, the seek() method doesn’t seem to advance the key to the specified position on the inner iterator (unless issuing getInnerIterator()->seek(x) directly and calling getInnerIterator()->current()). Reproduce code: --------------- <?php $iiter = new IteratorIterator(new ArrayIterator(range(0, 5))); $iiter->rewind(); $iiter->seek(2); var_dump($iiter->current()); $iiter->next(); // bus error var_dump($iiter->current()); /* End of file */ Expected result: ---------------- int(2) int(3) Actual result: -------------- int(0) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48816&edit=1
