<blockquote>
<p dir="auto">How is it possible for a program to rely on something guaranteed not to happen?</p>
</blockquote>
<p dir="auto">I don't see what's so hard to understand. If you have a destructor that performs an important operation, say unlocking a mutex, and if you fail to invoke that destructor for one of your objects, then your program might not work correctly. It might deadlock because other users of that mutex can never lock it.</p>
<p dir="auto">The point is that if your destructor doesn't do anything important, it's OK if the object is never destroyed. On the other hand, if you rely on resources being freed (to prevent memory exhaustion, or mutex deadlocks, or whatever) then you'd better destroy your objects not leak them. That needs to be said somehow, even if only as a note.</p>

<p dir="auto">No. But readers could assume it's undefined to fail to destroy any object with a non-trivial destructor, even if that destructor has no side effects. That's not a completely unreasonable position.</p>
</blockquote>
<p dir="auto">That is exactly why I think this line needs to be deleted, or at least reworded to not imply UB in a case where the behavior is actually quite well defined. If a reader makes that assumption, then they are misinterpreting the standard (I think, does anyone in CWG claim that this clause adds normative UB?)</p>
<blockquote>
<p dir="auto">if you rely on resources being freed (to prevent memory exhaustion, or mutex deadlocks, or whatever) then you'd better destroy your objects not leak them.</p>
</blockquote>
<p dir="auto">Conversely, it is possible to rely on the resources <em>not</em> being freed in some cases. If I actively choose not to call the dtor, I can rely on the effects not occurring. Or at least that is how I interpret the prior clause of the sentence. In those cases, I don't want the specter of UB dangling there in a perfectly well defined case.</p>
<p dir="auto">What would you want the note to say? I am struggling to think of anything that needs to be added to "the destructor shall not be implicitly called." That seems to clearly state the defined behavior, with little room for misinterpretation.</p>

<p dir="auto">I'm ambivalent. I can imagine using a <code class="notranslate">pmr::monotonic_buffer_resource</code> to allocate objects from a large block of storage, and then at the end of some series of operations declaring everything in that memory to be "dead". You can just use <code class="notranslate">pmr::monotonic_buffer_resource::release()</code> to discard all the memory without doing individual deallocations. It might also make sense to skip running individual destructors. If you started a second series of operations that allocated from that storage again for new objects, you'd be reusing the storage.</p>

Otherwise, you might be leaking memory or file descriptors or mutex locks. On the other hand, if your destructors are, in fact, trivial, nothing is lost by calling them (they will be no-ops anyway, and the calls very likely optimized away).</p>

Maybe the destructors perform a "commit" step, and if you want to abandon the set of operations without committing, you just "leak" all the objects, so nothing is committed. I'm not saying that's the best way to design the system, but I bet somebody's done it, and do we gain anything by making that undefined?

This is explicitly one of the motivations behind re-using memory pools with pmr allocators, where you determine everything in the pool has destructors that only release memory also in the pool - and so simply reclaim the pool when the whole data structure is no longer needed.
