<pre>Example: <a href="https://godbolt.org/z/cx4fbzvqb">https://godbolt.org/z/cx4fbzvqb</a>
In this example, user provided a operator new with side effects (print). From
the language side, the program should print the times we create coroutine
frame. However, since the compiler made coroutine elision optimization, all the
call to provided new are removed. So from the language side, it looks like a
compiler bug.</pre>
