This assertion fails since 2.086.0-beta.1: https://run.dlang.io/is/YvQvyE struct Quat { static struct Vec { int x; } union { Vec v; struct { float x; } } static Quat identity() { Quat q; q.x = 1.0f; return q; } } struct QuatContainerWithIncompatibleInit { Quat q = Quat.identity; } void main() { QuatContainerWithIncompatibleInit c; assert(c.q.x == 1.0f); // fails }
