This bug has been fixed in CVS.

Thank you for the report, and for helping us make PHP better.
FYI: Your expected result is wrong, PHP allows you to "decode"
non-valid JSON data:
json_decode("foo"); // string(3) "foo"
json_decode('"'); // string(1) """

Description:
------------
JSON Version 1.2.1
The following program causes PHP to exit with a segmentation fault:
<?php
json_decode("\"");
?>
Instead, it should fail gracefully ("\"" is not valid JSON) and return
NULL.
The <a href="http://www.json.org/JSON_checker/">JSON
checker</a>
correctly reports that it is invalid input:
"syntax error at character 0"
Reproduce code:
---------------
<?php
print_r(json_decode("\""));
?>
Expected result:
----------------
NULL
Actual result:
--------------
Segmentation fault (core dumped)
