Is this the expected behavior? Thanks.

Yep.

No it's not:

import std.stdio;

struct foo {
        size_t  _a;

        this(const size_t b) const {
                this._a = b;
        }
}

class bar {
        size_t  _a;

        this(const size_t b) const {
                this._a = b;
        }
}

void main() {
        const a = new foo(42);
        const b = new bar(42);
        writefln("a._a: %d\n", a._a);
        writefln("b._a: %d\n", b._a);
}

works as expected. dmd v2.058
