Bug 19099 – Struct with field that has postblit or destructor makes struct assignable

struct B { //this(this) {} //~this() {} int a; } struct A { B b; immutable int a; this(int b) { a = b;} } void main() { import std.stdio : writeln; A a = A(2); writeln(a.a); A b = A(3); a = b; // line 21 writeln(a.a); } This code correctly yields : bug.d(21): Error: cannot modify struct a A with immutable members However, if the postblit or the destructor or commented (or both), the code compiles successfully and when ran it prints: 2 3
