Try the following:
# rm config.cache
# ./configure --disable-all --disable-cgi --enable-ftp --enable-debug
# make clean && make
And then run the script:
# gdb sapi/cli/php
(gdb) run ftptest.php
.

Just realised, one thing I haven't mentioned (!) is that I'm running
this as a command line script (php test.php).
Here's the backtrace (looks like it's when it's trying to deallocate
stuff)
(gdb) bt

Looks like it's dying after the dump:
[EMAIL PROTECTED] /root]# php test.php

<?php
$fp = ftp_connect("ftp.nai.com");
var_dump($fp);
ftp_login($fp, "anonymous","[EMAIL PROTECTED]");
var_dump($fp);
var_dump(ftp_nlist($fp,"/"));
var_dump($fp);
?>

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

I can't reproduce a crash with the code snippet provided using 4.3.3 on
a 2.4.21 kernel.
Please provide the ./configure line used to compile PHP and note on
which line (I'm assuming the nlist line itself) the crash occurs.
