^^ You are actually right on this. I was not taking into account that
JSON_NUMERIC_CHECK's actual purpose is to look for strings of numeric values
and automatically convert them to int values. In my example of forcing a string
type on the numeric string, would still require NUMERIC_CHECK to reformat the
var type.
I was simply using JSON_NUMERIC_CHECK to ensure all my number values were
integers, the fact that my platform may use a long set of numbers with no alpha
chars in a "tracking number" field would break my implementation was not
considered.
I'm closing the bug, I'll have to just make sure I'm forcing int values where I
require it manually.
Thanks!

I think your are running in 32-bit os,
and I think it is not a bug, since the number value exceed the PHP_INT_MAX.

I would further like to add that even if I FORCE the numeric string to be of a
string type in the array before passing it to json_encode(), the encode still
treats the string encapsulated number as a LONG and not as a string.
There is definitely a bug here.

Incorrect ACTUAL output entered in bug, here is the real actual output:
{"test":3.43434343434e+15}

Description:
------------
json_encode will produce undesired results when used with JSON_NUMERIC_CHECK
when one or more values is longer than 12 digits, ex: 3434343434343434. The
resulting JSON encoded string has the above value listed as: 3434343434340000.
Removing the JSON_NUMERIC_CHECK option fixes the problem, but then all other
numeric values are returned as strings rather than integers.
Test script:
---------------
$test = array("test"=>3434343434343434);
$test = json_encode($test, JSON_NUMERIC_CHECK);
echo $test;
Expected result:
----------------
{"test":3434343434343434}
OR
{"test":"3434343434343434"}
Actual result:
--------------
{"test":3434343434340000}
