This test is to ensure that `cjson.encode()`
|
|
can encode large JSON strings correctly,
|
|
the JSON string is the string element in JSON representation,
|
|
not the JSON string serialized from a Object.
|
|
|
|
The bug is caused by the overflow of the `int`,
|
|
and it will casue the signal 11 when writing the string to buffer.
