Another test case which makes base_convert dump core is this:
<?php
$x=base_convert ("2f0f336509c9a3d0f29e4281321d496f", 16, 36);
echo $x;
echo Done;
?>
I have not experienced this problem under SuSE 7.2 but under the
following:
Mandrake 8.2
Linux p700 2.4.18-6mdk #1 Fri Mar 15 02:59:08 CET 2002 i686 unknown
apache-1.3.23-4mdk

apache-modules-1.3.23-4mdk

your testcase can be reduced to:
<?php
$data =
"612533413525334125374269253341312533426125334135253341253742692533413025334273253341312533412532323025323225334269253341312533427325334131253341253232302532322533426925334132253342732533413125334125323230253232253342692533413325334273253341312533412532323025323225334269253341342533427325334131253341253232302532322533422537446925334132253342612533413525334125374269253341302533427325334131253341253232302532322533426925334131253342732533413125334125323230253232253342692533413225334273253341312533412532323025323225334269253341332533427325334131253341253232302532322533426925334134253342732533413125334125323230253232253342253744692533413325334261253341352533412537426925334130253342732533413125334125323230253232253342692533413125334273253341312533412532323025323225334269253341322533427325334131253341253232302532322533426925334133253342732533413125334125323230253232253342692533413425334273253341312533412532323025323225334225374469253341342533426125334135253341253742692533413025334273253341312533412532323025323225334269253341312533427325334131253341253232302532322533426925334132253342732533413125334125323230253232253342692533413325334273253341312533412532323025323225334269253341342533427325334131253341253232302532322533422537446925334135253342612533413525334125374269253341302533427325334131253341253232302532322533426925334131253342732533413125334125323230253232253342692533413225334273253341312533412532323025323225334269253341332533427325334131253341253232302532322533426925334134253342732533413125334125323230253232253342253744253744";

you are trying to base_convert a number with > 1500 digits. this is not
going to work! but it shouln't crash,
i agree. (no time to fix it right now)

Running the following always causes a core dump:
<?php
$arr = array (
1 => array ("0","0","0","0","0"),
2 => array ("0","0","0","0","0"),
3 => array ("0","0","0","0","0"),
4 => array ("0","0","0","0","0"),
5 => array ("0","0","0","0","0")
);
print_r($arr);
echo "<br>\n\n<br>\n\n";
$str = serialize($arr);
echo "serialized<br>\n", $str, "<br><br>\n\n";
function hex2bin($data) {
$len = strlen($data);
return pack("H" . $len, $data);
}
$enc = urlencode($str);
echo "urlencoded<br>", $enc, "<br><br>\n\n";
$gzd = gzcompress($enc);
//echo "gzcompressed (urlencoded)<br>", $gzd, "<br><br>\n\n";
$b64 = base64_encode($gzd);
echo "base64_encoded<br>", $b64, "<br><br>\n\n";
$b2h = bin2hex($enc);
echo "bin2hex (urlencoded)<br>", $b2h, "<br><br>\n\n";
$binary = base_convert($b2h, 16, 2);
echo $binary, "<br><br>\n\n";
$conv = base_convert($binary, 2, 16);
echo $conv, "<br><br>\n\n";
$h2b = hex2bin($conv);
echo $h2b, "<br><br>\n\n";
$md = md5($str);
