Bug 19680 – [REG2.085.0-beta.1] Uda inside union breaks default initialization

Code: ---- struct MyInnerStruct { union { @("BRAKE_ME") int[2] v = 0; struct { int x, y; } } this(int vx, int vy) { x = vx; y = vy; } } struct MyStruct { MyInnerStruct inner = MyInnerStruct(1, 2); } void main() { { MyStruct ok = MyStruct(); assert(ok.inner.v == [1, 2]); } { MyStruct err; assert(err.inner.v == [1, 2]); } } --- run.dlang.io: https://run.dlang.io/is/fzj0IM

It seems to be fixed in dmd-2.085.0-beta.2 and later. As run.dlang.io does not contain beta versions, I can reproduce this bug only locally. I don't know if this issue should be closed, if there is no track of what change has fixed the problem.

This is fixed and the regression has not been shipped. I think that the culprit was a PR supposed to simplify how something is made in intern but has been reverted.
