Bug 4632 – Copy constructor not invoked on array reallocation

Struct copy constructor is not invoked on array copy, expansion nor concatenation; but it should. -------------------- array_cpctor.d void main() { auto ss = new S[](1); auto ssdup = ss.dup; // A copy is created... assert(&ss[0] != &ssdup[0]); // but the copy constructor is not invoked! assert(ssdup[0].copy); // Assertion failure } struct S { bool copy; this(this) { copy = true; } } -------------------- % dmd -run array_cpctor.d core.exception.AssertError@array_cpctor(10): Assertion failure --------------------

Might be the same as bug 3475
