Correction, the fix I referred to above didn't make it into the "Feb
13, 2003 22:30 GMT" snapshot, grab one that comes *after* that (i.e.
Feb 14, 2003 00:30 GMT)

I'm trying to understand the problem you're having, but I'm seeing some
slightly conflicting information so I'd like to figure out if I'm
reading you incorrectly...
Running the following script using the php CLI executable, what is the
*exact* output? (I'm just using ftp.kerneli.org as a known public ftp
server for the sake of example)
<?php
$fp = ftp_connect("ftp.kerneli.org");
var_dump($fp);
ftp_login($fp, "anonymous","[EMAIL PROTECTED]");
var_dump($fp);
var_dump(ftp_nlist($fp,"/"));
var_dump($fp);
?>
Don't take this request as demeaning or belittleing, I'm just trying to
approach this problem one step at a time.
Note: be sure to grab the latest snapshot (Dated after: Feb 13, 2003
21:00 GMT) before you try this out, I've just recently fixed a segfault
in the ftp extension which *may* be related.

Cannot replicate the bug on Linux using the latest CVS, possibly a BSD
only issue. Can you reproduce the crash using PHP's CLI sapi?
The backtrace does not indicate the the crash is the result of PHP
code, but rather something in Apache code(?).

Spider,
The Stable branch is still breaking somewhere along the ftp
ftp_*list functions in FreeBSD5. These errors don't appear with the
list command commented out. Please Take note that it is now
seg-faulting twice as opposed to once as well as killing 2 child
procs:
tail - /var/log/httpd-error.log
