I have the same problems with a script under freebsd4.5-release.
It just started crasching out of nothing. No change in the dirscancode,
no change on the server. Worked just fine before yesterday. The only
way to run the script now is to press the updatebutton in
internetexplorer several times quite quickly, it works when I do so (I
get about 5-6 httpds wotrking in the background).
This is so strange.

The option is --enable-debug, right? --with-debug appeared to do
nothing. When compiled with --enable-debug, the script did not crash.
But it certainly crashes with a normal build without debugging.

I'll compile PHP from source with debugging and test tomorrow. Can't
do it today since I just changed the code to exec find, and it already
processed today's files (is a webserver log processing helper script).
You're right, I know about the 0/false issue, but I was lazy since all
the filenames will always be fully qualified hostnames :)
I don't remember exactly how many times readdir() was being called
before it crashed, but probably somewhere between 100-200. When it
first crashed, I noticed I had been calling that function a lot without
using closedir(), but after I added it and only called it once on a
single directory, it still crashed.

Can you enable --with-debug please and post a backtrace?
Btw, how often have you to call readdir() until it crashes?
Btw, your code won't work for directories containing files or dirs
naming like '0'; see the manual page and use 'while (false !== ($s =
readdir() ...'
Also, can you try the source relese itself please and not a/the port?

readdir() is consistently crashing PHP in one of my scripts.
Unfortunately, I can't reproduce the problem with a small test script,
for some reason. However, the function that is causing PHP to scrash
is shown below. It is crashing after a number of readdir() calls:
function list_dir($name)
{
$d = opendir($name);
while ($s = readdir($d))
if (($s != ".") && ($s != ".."))
$a[] = $s;
closedir($d);
return isset($a) ? $a : false;
}
This is the CGI version, running from the command line. A backtrace is
shown below:
(gdb) bt
#0 0x286ed20d in readdir_r () from /usr/lib/libc.so.4
#1 0x80dbd9b in php_if_readdir ()
#2 0x8146e04 in execute ()
#3 0x8146ffd in execute ()
#4 0x8146ffd in execute ()
#5 0x8146ffd in execute ()
#6 0x8129418 in zend_execute_scripts ()
#7 0x806e6be in php_execute_script ()
#8 0x806c8d0 in main ()
#9 0x806bcd3 in _start ()
I can provide more information if necessary. PHP was compiled from
ports within the last week.
