Remember though that when emplacing a class over some memory, you must account for any extra alignment (though that doesn't seem to
be a problem here).

emplace does do a check for misalignment this internally with the
testEmplaceChunk helper function. It would throw otherwise.

Right, emplace *checks*, which means caller must take it into account. This doesn't explain the issue, but it should be kept in mind when making the allocation, and building the slice. OP clearly just assumed his slice would be aligned.
