#36581 [Com]: Segment fault doing directory recursion stuff

ID: 36581 Comment by: judas dot iscariote at gmail dot com Reported By: t dot stobbe at blackdogdev dot com Status: Open Bug Type: Reproducible crash Operating System: Debian (sarge): 2.4.27-2.i386 PHP Version: 5.1.2 New Comment: Well.if you try to use a "modern" thing like RecursiveDirectoryIterator it also segfaults ?? http://www.php.net/~helly/php/ext/spl/classRecursiveDirectoryIterator.html most likely you are triggering an infinite loop. Previous Comments: ------------------------------------------------------------------------ [2006-03-02 02:17:07] t dot stobbe at blackdogdev dot com Description: ------------ I'm trying to do stuff recursively on a filesystem. To simplify, call do_path($path) { $dh = opendir($path) ... if (is_dir($file)) { do_path($path . $file); } else { process_file($path . $file); } Of course I'm checking for "." and ".." to prevent infinate loops. proccess_file() loads the file contents and does regex stuff on it. After 4 subdirectories in, and processing about 1000 files, it crashes with a segment fault. I've even tryed manually unsetting all vars after being used, but to no avail. It crashes at the same place in the file system each time. Reproduce code: --------------- Email me. I can't post the code and it's way to large. Expected result: ---------------- All files and directories (within reason) would be processed properly, similar to the way `du' works. Actual result: -------------- Program received signal SIGSEGV, Segmentation fault.
