Sorry, might help to mention that I did try the function first without
using globals and returning the directory file_count and adding it up
and returning the total, also had the same problem.

I get this all the time when I include a recursive function call. I've
tried rewriting the function several ways and get intermitten
Segmentation faults, saw a SuSe Linux report about scripts terminating
with similar output in the web server error_log.
I"ve tried just opening the fh and going down recursive directories
with this, got the seg faults often.This version
buffers the file names in an array, closes the directory handle then
processes the array, to count certain types of files in the directory
tree. Still segfaults often enough to make it unreliable. I turned on
the autoflush in php.ini and it dies in this routine.
FreeBSD 4.5-RELEASE
Apache/1.3.26 (Unix) PHP/4.2.2 mod_ssl/2.8.9 OpenSSL/0.9.6g
RegisterGlobals = On :)
I use a perl script for my apache coplilation, here's my php_config
line.
--with-mysql=/usr/local --with-gd=/usr/local
--with-jpeg-dir=/usr/local/lib --with-png-dir=/usr/
local/lib --with-zlib-dir=/usr/lib $xpm
--with-freetype-dir=/usr/local/lib --with-mcrypt=/usr/local
--with-gettext --wit
h-xml --with-zlib=/usr --with-bz2=/usr/local --with-zip=/usr/local
--with-mm=/usr/local --with-apache=../$apache --enable-ftp
--disable-debug --enable-track-vars
Here's the current version of the function
function CountFiles($dir,$d) {
global $home;
global $prod_count;
$farray = array(); $d++;
if (is_dir("$home$dir")) {
print "<!-- ISDIR dir=$dir level=$d -->\n";
if ($dfh = @opendir("$home$dir")) {
while (($fil = readdir($dfh)) !== false) {
if (!preg_match("/^\.+$/", $fil)) {
array_push($farray,"$fil");
}
}
closedir($dfh);
if (count($farray) > 0) {
while (list ($key, $file) = each ($farray)) {
if (is_dir("$home$dir/$file")) {
CountFiles("$dir/$file",$d);
flush();
} else if (preg_match("/^thumb_\w+\.|\.wav$|\.aif$/", $file)) {
$prod_count++;
print "<!-- POST dir=$dir/$file prod_count=$prod_count -->\n";
flush();
}
}
}
}
}
flush();
}
It's not entirely reproducible, but once I got a directory where it
causes the segfault I can comment out this routine and it's okay,
comment it back and reload and it segfaults.
So in that sense it's reproducible. Restarting the web server has no
effect. Though if I reload enough times sometimes the script completes,
there is definitely some sort of bug, maybe the filehandle or array
declaration isn't local or leaks out, not sure.
Hope it's not something stupid I overlooked. :)
