Yes, it is fixed in the current CVS, I used, php4-200111150000

I could even increase max to 300 and it worked. However, when submitting my test script with no
files inserted for upload, the values of the file uploads were not "none", but a temporary
file. Unexpected behaviour which may lead to problems. The size of the (temp)files is 0, but the
value of the variable should be "none" or "".

Cannot reproduce with current CVS.

Can you try a snapshot from snaps.php.net and report back if that fixes the problem?

<!-- example that causes the error -->
<!-- you don't need to upload any files, just clicking Submit will cause the crash -->
<form method=post enctype="multipart/form-data">
<?

if (is_array($file))
  while (list($key,$val) = each($file))
    print "$key => $val<br>\n";

# changing max to 33 will not cause the segfault, 34 will.
$msx = 34;

for ($i=0;$i<$msx;$i++) {
  print $i.'Upload file: <input type=file
name="file['.$i.']"><br>';
}

?>
<input type=submit>
</form>

<--end of example -->

--with-mysql=/usr --enable-sysvshm=yes --enable-sysvsem=yes --enable-versioning --with-gd=/usr
--enable-track-vars=yes --enable-force-cgi-redirect=yes --enable-memory-limit=yes
--with-apache=../apache_1.3.19 --enable-debug=no --with-mcrypt

Page works if I switch back to php 4.0.4-pl1
