ecs_struct gives error: xxx matches with actual type but alignment is different

[xubury]

With the following code snippet, ecs_struct gives error:
error: meta.c: 283: computed size for 'versor' matches with actual type but alignment is different (4 vs. 16)

  typedef __attribute((aligned(16))) float versor[4];
  ECS_COMPONENT(ecs, versor);
  ecs_struct(ecs, {.entity  = ecs_id(versor),
                   .members = {{.name = "x", .type = ecs_id(ecs_f32_t)},
                               {.name = "y", .type = ecs_id(ecs_f32_t)},
                               {.name = "z", .type = ecs_id(ecs_f32_t)},
                               {.name = "w", .type = ecs_id(ecs_f32_t)}}});

 EcsComponent const *ptr = ecs_get(ecs, ecs_id(versor), EcsComponent);
 printf("%d", ptr->alignment); // output 16

Can anyone show me where I did wrong? Many thanks!

Found a workaround by doing this, it seems like alignment is mismatch with ECS_COMPONENT and ecs_struct?

  ecs_entity_t ecs_id(versor) = 0;
  ecs_id(versor) = ecs_array(ecs, {.entity = 0, .type = ecs_id(ecs_f32_t), .count = 4});
  ecs_get_mut(ecs, ecs_id(versor), EcsComponent)->alignment = 16; // serialization will be incorrect without this

Yeah ECS_COMPONENT gets the actual alignment of a type, whereas ecs_struct calculates the alignment. This should be fixed, ecs_struct should not override the actual alignment of a type.

Fixed!
