I'm afraid they do. The check answers the question "If I put this type into a struct, where will the compiler align it?", which is ultimately what our code is interested in, and it also happens to correspond to GCC's __alignof__ operator, hence the name. If you want to answer a question of the form "If I put this type at this address, will my program crash?", you can write a different test, but it would be a lot more cumbersome and won't get you substantially better results. -- Peter Eisentraut [EMAIL PROTECTED]
