Comment (by marshall):

 I don't think this is a bug.

 If you catch the exception, and display the `what()`, it says:`bad lexical
 cast: source type value could not be interpreted as target`.

 I believe that what has happened is that it attempted to convert the two
 character sequence `"0\0"` to an integer, and that failed. This is the
 same thing that would happen if you appended (say), a 'Z' instead of a
 '\0'.

 Why would you expect that to succeed?
