Isn't this a distinct problem or am I wrong? This is not only about
8-byte boundaries.

OpenCL requires all types to be naturally aligned.

To the best of my knowlegde, D only supports align(1) and align(4). On
the other hand, compile time introspection allows my CUDA api to convert
alignment correctly for any given struct.
gotta look that up in your code.
Maybe I also find some other ideas for writing m

The idea, that I suggested to the LDC team too, is to extend the semantics of
align, no new syntax seems needed:
align(8) alias int[4] Foo;
align(8) double good;

me to ask for that feature here.
Original post:

OpenCL requires all types to be naturally aligned.
The D specs state:
"AlignAttribute is ignored when applied to declarations that are not
struct members."
