Operating system: Linux (Ubuntu)
PHP version: 5.2.3
PHP Bug Type: Reproducible crash
Bug description: json_decode causes segmentation fault
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)
