/*
* Test that duk_hbufferobject is memory safe when the underlying dynamic
* buffer is a dynamic buffer that is resized after creation. In particular,
* the testcase attempts to cover memory safety issues related to an
* underlying buffer not covering the logical duk_hbufferobject view.
*
* The exact results of "uncovered" operations are not very important and
* not always intuitive: an uncovered buffer is not considered normal buffer
* usage but its memory safety matters.
