Apologies for the late answer. I noticed that Jan asked the following
question on v5:
"Do you really need 8-byte alignment even on 32-bit Arm?"
We forbid unaligned access on 32-bit Arm (and unaligned access should be
avoided on 64-bit), so if the structure contains a 64-bit type, then we
definitely need the data to be 8-byte aligned.
What is the expected alignment of the structure?
Cheers,
