Pseudo-destructor calls\r\n\u003e \r\n\u003e In the current C++ language rules, \"pseudo-destructor\" calls may be used in generic code to allow such code to be ambivalent as to whether an object is of class type:\r\n\u003e \r\n\u003e ```c++\r\n\u003e template\u003ctypename T\u003e void destroy(T *p) { p-\u003e~T(); }\r\n\u003e ```\r\n\u003e \r\n\u003e When T is, say, int, the pseudo-destructor expression p-\u003e~T() is specified as having no effect. We believe this is an error: such an expression should have a lifetime effect, ending the lifetime of the int object. Likewise, calling a destructor of a class object should always end the lifetime of that object, regardless of whether the destructor is trivial.\r\n\u003e \r\n\u003e This change improves the ability of static and dynamic analysis tools to reason about the lifetimes of C++ objects.\r\n\r\nSo doesn’t the statement `0 .T::~T();` given in [[expr.prim.id.dtor]/3](https://timsong-cpp.github.io/cppwp/expr.prim.id.dtor#3) produce undefined behavior now that it destroys the temporary object 0 twice?\r\n\r\n\u003e [*Example 1*:\r\n\u003e \r\n\u003e ```c++\r\n\u003e struct C { };\r\n\u003e void f() {\r\n\u003e   C * pc = new C;\r\n\u003e   using C2 = C;\r\n\u003e   pc-\u003eC::~C2();     // OK, destroys *pc\r\n\u003e   C().C::~C();      // undefined behavior: temporary of type C destroyed twice\r\n\u003e   using T = int;\r\n\u003e   0 .T::~T();       // OK, no effect\r\n\u003e   0.T::~T();        // error: 0.T is a user-defined-floating-point-literal ([lex.ext])\r\n\u003e }\r\n\u003e ```\r\n\u003e \r\n\u003e — *end example*]","author":{"url":"https://github.com/geryogam","@type":"Person","name":"geryogam"},"datePublished":"2021-09-27T07:28:55.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":18},"url":"https://github.com/4944/draft/issues/4944"}</script>

Pseudo-destructor calls\r\n\u003e \r\n\u003e In the current C++ language rules, \"pseudo-destructor\" calls may be used in generic code to allow such code to be ambivalent as to whether an object is of class type:\r\n\u003e \r\n\u003e ```c++\r\n\u003e template\u003ctypename T\u003e void destroy(T *p) { p-\u003e~T(); }\r\n\u003e ```\r\n\u003e \r\n\u003e When T is, say, int, the pseudo-destructor expression p-\u003e~T() is specified as having no effect. We believe this is an error: such an expression should have a lifetime effect, ending the lifetime of the int object.

href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2020/p0593r6.html#pseudo-destructor-calls" rel="nofollow">P0593R6</a>, a pseudo-destructor call ends the lifetime of a scalar object:</p>
<blockquote>
<p dir="auto">3.6. Pseudo-destructor calls</p>
<p dir="auto">In the current C++ language rules, "pseudo-destructor" calls may be used in generic code to allow such code to be ambivalent as to whether an object is of class type:</p>
<div class="highlight highlight-source-c++ notranslate position-relative overflow-auto" dir="auto" data-snippet-clipboard-copy-content="template&lt;typename T&gt; void destroy(T *p) { p-&gt;~T(); }"><pre class="notranslate"><span class="pl-k">template</span>&lt;<span class="pl-k">typename</span> T&gt; <span class="pl-k">void</span> <span class="pl-en">destroy</span>(T *p) { p-&gt;<span class="pl-en">~T</span>(); }</pre></div>
<p dir="auto">When T is, say, int, the pseudo-destructor expression p-&gt;~T() is specified as having no effect. We believe this is an error: such an expression should have a lifetime effect, ending the lifetime of the int object. Likewise, calling a destructor of a class object should always end the lifetime of that object, regardless of whether the destructor is trivial.</p>
<p dir="auto">This change improves the ability of static and dynamic analysis tools to reason about the lifetimes of C++ objects.</p>
</blockquote>
<p dir="auto">So doesn’t the statement <code class="notranslate">0 .T::~T();</code> given in <a href="https://timsong-cpp.github.io/cppwp/expr.prim.id.dtor#3" rel="nofollow">[expr.prim.id.dtor]/3</a> produce undefined behavior now that it destroys the temporary object 0 twice?</p>
