ID: 48816 Comment by: jan-phpbug at kantert dot net Reported by: kim at burgestrand dot se Summary: IteratorIterator seek() causes bus error Status: Assigned Type: Bug Package: SPL related Operating System: Mac OS 10.5.7 PHP Version: 5.3.0 Assigned To: colder New Comment: I can reproduce the problem in stock Ubuntu 10.04 lucid on 86_64/amd64. PHP 5.3.2-1ubuntu4.2. Results in a segmentation fault! We experienced similar problems with iterators at other points in our code. 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] paj...@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 doesnt 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/bug.php?id=48816&edit=1
