Crashes both on windows and linux, both m32 and m64. Tested with 2.066, 2.066.1, master --- struct Vector() { } struct ChunkCoord { union { struct { short x; } Vector!() vector; } } struct Chunk { this(ChunkCoord) { coord = coord; } ChunkCoord coord; static Chunk* unknownChunk = new Chunk(ChunkCoord()); } ---
