Bug description:A particular string fails to decompress

Description:
------------
We use gzdeflate to compress search parameters. When we recently upgraded
from 5.3.8 to 5.4, a slew of error messages appeared. See the test script
below. We've tried to minimize it, but any changes do not cause the error
to trigger.

Changing the variable name "region_id" to "egion_id" results in 90.
Changing the variable name "region_id" to "tegion_id" causes the same
error.
Changing the variable name "discipline" to "isciplined" results in 92.

Changing the value assigned to region_id from 1 to 2 results in 92.
Changing the value assigned to region_id from 1 to 4 results in an error.

Test script:
---------------
$array = array(
        'region_id' => 1,
        'discipline' => 23,
        'degrees' => array(),
        'country_id' => 27
);

$serialized = serialize($array);

$deflated = gzdeflate($serialized, 9);
$inflated = gzinflate($deflated);

echo strlen($inflated);

Expected result:
----------------
Expected: 92

Actual result:
--------------
Warning: gzinflate(): data error in D:\Web\Projects\Bench\index.php on line
