it is an error not a warning.

i'm a bit confused: was it completely broken (as this statement suggest)
or was the generated code correct when alignment was ensured by user
code (as stl's statement suggested)?

well, isn't it an ABI change if you need to recompile everything with a
specific compiler version? users will run into exactly the same issue,
if they use structs as my tagged_index, which is not under their control.
