I had to search for this, but managed to find the relevant mlugg@ comment[0] on the ZSF zulip: > i had to change the bytes field from [*]align(@alignOf(T)) u8 to just [*]u8 (and cast the alignment back in the like one place that field is accessed). this wasn't necessary for MultiArrayList in and of itself, but it was necessary for embedding a MultiArrayList(T) inside of T without a dependency loop, like const T = struct { children: MultiArrayList(T), }; // reproduced for completeness: fn MultiArrayList(comptime T: type) type { return struct { bytes: [*]align(@alignOf(T)) u8, // ... }; } [0]: https://zsf.zulipchat.com/#narrow/channel/454360-compiler/topic/type.20resolution/near/533972426 https://zsf.zulipchat.com/#narrow/channel/454360-compiler/to...
