I was thinking about it a bit more, and I think some serious profiling data should be gathered, i.e. how often it is called with aligned pointers.

I think this function itself is rarely used?
And if it is, it may often be used to search trough strings?
And in such case the pointers will be not aligned very often?

I mean, is this really worth of effort? Only some profiling of real applications can tell.

But it was nice mental exercise anyway. Smile
