Description:
------------
gzuncompress() does not report error if $limit > 0 but too short for
data being uncompressed.
Problem is PHP specific; test OK on latest php 5.2 and 5.3 snaps.
I will be dropping new PHPT shortly for gzuncompress(); the PHP 6 tests
will be tagged with a XFAIL because of this defect.
Reproduce code:
---------------
<?php
$data = b'string_val';
$compressed = gzcompress($data);
var_dump(gzuncompress($compressed, strlen($data)));
var_dump(gzuncompress($compressed, 1));
?>
Expected result:
----------------
Expected output (based on output for same script when run on 5.2/5.3)
string(10) "string_val"
Warning: gzuncompress(): buffer error in <...> on line 5
bool(false)
Actual result:
--------------
string(10) "string_val"
string(10) "string_val"
