Bug description: PHP crashes using the zip functions
The zip functions in PHP4.1.1 appears to be causing PHP to crash with a
segmentation fault. When using it in my project I get a "document contains
no data".
I borrowed the script used in a previous bug report.
<?php
$zip = zip_open("test_zip.zip");
if ($zip) {
echo "Ok, entering while..\n";
while ($zip_entry = zip_read($zip)) {
echo "In while..\n";
echo "Name: " .
zip_entry_name($zip_entry) . "\n";
echo "Actual Filesize: " .
zip_entry_filesize($zip_entry) . "\n";
echo "Compressed Size: " .
zip_entry_compressedsize($zip_entry) . "\n";
echo "Compression Method: " .
zip_entry_compressionmethod($zip_entry) . "\n";
if (zip_entry_open($zip, $zip_entry, "r")) {
echo "File Contents:\n";
$buf = zip_entry_read($zip_entry,
zip_entry_filesize($zip_entry));
echo "$buf\n";
zip_entry_close($zip_entry);
}
echo "\n";
}
zip_close($zip);
}
?>

The zip was created using the zip.lib.php library used in phpMyAdmin but
the zip does work and the error still occurs when a zip is created using
the zip command on linux.
[leigh@eden debug]$ unzip test_zip.zip

The zip file I used can be downloaded from:
http://www.sitebox.org/test_zip.zip
I used zziplib-0.10.27 to compile PHP with zip support.
