[PHP-DEV] PHP 4.0 Bug #8463: Using internal function in usort call segfaults From: greg <email protected>

Bug description: Using internal function in usort call segfaults

Using usort() with an internal function segfaults, for example using strcasecmp() in the usort call will fail, but making a function in php called testcmp() which then calls strcasecmp() works fine.

This worked in 4.0.3 and below

In the following code snipit, the script will print 1 and 2 but crash before 3.

$mblist[0] = "Drafts";
$mblist[1] = "LRP";
$mblist[2] = "Sent Items";
$mblist[3] = "INBOX";
$mblist[4] = "Apache";
$mblist[5] = "Internet";
$mblist[6] = "Lists";
$mblist[7] = "People";
$mblist[8] = "Personal";

Function testcmp( $a, $b )
        {
        return strcasecmp( $a, $b );
        }

echo "1<BR>";
flush();
usort( $mblist, testcmp );
echo "2";
flush();
usort( $mblist, strcasecmp );
echo "3";
flush();
