It crashes on a split function, can you try to shorten your script to narrow the search for us?

Derick

Looks like you're correct..  I added a trim() around the second paramater of split() and it seems to take care of it.  

It would seem that there's no checking done on the size parameter in php_split before calling add_next_index_stringl for the last value.

line number is ext/standard/reg.c:574 in php4.2.2dev

Snippet of code (offending line marked by >>>> <<<<), $sHeader is returned by curl_exec):
class HeaderObj {
	function HeaderObj($sHeader) {
		$this->header = $sHeader;
		$aHeaders = Array();
>>>>
		$aLines = split("\n",$sHeader);
<<<<

		foreach($aLines as $sLine) {
			$temp = split(":",trim($sLine));
			$aHeaders[$temp[0]] = (isset($temp[1])) ? trim($temp[1]) : "";
			if ($temp[0] == "Content-Type") {
				if (!isset($temp[1])) {
					$aHeaders[$temp[0]] = trim("text/html");
				}
			}
		} 
		if (!isset($aHeaders['Content-Type'])) {
			$aHeaders['Content-Type'] = "text/html";
		}
		$this->headers = $aHeaders;
		$this->headers['string'] = $sHeader;
		reset($this->headers);
	}
}

If I put it in a trim(), with --enable-debug, I get this warning:

Firs try this snapshot:

http://snaps.php.net/php4-latest.tar.gz

And if it does not work, give a short, complete and standalone script which can easily be used to reproduce this. As it seems the crash happens in split(), come up with such script that does NOT include anything but it and the data that crashes it.

More info:  I managed to solve the problem by applying the following:

593,595c593,595
<
<       add_next_index_stringl(return_value, strp, size, 1);
<
---
>       if (size > 0) {
>               add_next_index_stringl(return_value, strp, size, 1);
>       }

Don't know if this is a good solution or not.  I will try the latest snapshot tomorrow and see if the problem is solved.

Cheers.

If it's not fixed in the snapshot (might not be) please
provide us the patch against it (diff -u) and add it here..

No feedback..should be fixed in 4.2.3 though.
