&gt; Something as core as proper stack handling is to me basic functionality.<p>rustc handles it just as much as other compilers do. It should be safer than that, but it&#x27;s currently not due to a compiler bug, and features making it safer are not &quot;basic stack handling&quot;.<p>This is <i>not</i> undefined behavior, as has been said multiple times in this thread; please stop repeating this lie. This is a deterministic crash that can&#x27;t be exploited easily.<p>&gt; And, any project which resents such technical &#x2F; conceptual criticism leaves one with much to ponder.<p>No, their comment said &quot;inflammatory&#x2F;unnuanced&#x2F;ill-informed criticism&quot;. Which yours is.
