The input doesn't seem to be valid JSON.

Assuming you want the test property to contain the literal string a\b\c\d\e\f\g, you need to encode the backslashes twice - once for the string literal value within the serialized object, and again for the JSON representation of that string:
JavaScript
var json_problem = '{"test": "a\\\\b\\\\c\\\\d\\\\e\\\\f\\\\g"}';
var parsed_json_problem = JSON.parse(json_problem);
Pasting your string (including the 's) into jsonlint.com gives:
Quote:
Error: Parse error on line 1:
'{"test": "a\\b\\c\\
^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'
I can only assume you pasted it in without the 's, in which case you would only need to escape the backslashes once.

With your original code, the string property would contain a literal a, a backspace character (\b), three invalid characters (\c, \d, \e), a form-feed character (\f), and another invalid character (\g). This value cannot be deserialized, which is why you're getting an error.
