Bug 19393 – Structure dtor isn't called after passed to T[]... argument. Memory leaks issue

import std.stdio; struct S { void* ptr; int counter = 1; ~this() @nogc { debug writeln(--counter, ", destructor"); } this(this) @nogc { debug writeln(++counter, ", postblit"); } } void foo(const(S)[] ar...) @nogc { auto d = ar[0]; } void bar() @nogc { foo(S(null)); } void main() { bar(); } --------- output: 2, postblit 1, destructor --------- expected output: 2, postblit 1, destructor 0, destructor The final, second, destructor is never called. This can cause memory leaks.
