Well, *now* there's a plan to fix it :)
Yes, I was just about to report the same thing. By the way, it also looks like boost.function is sensitive to packing/alignment (in particular, the small-object optimizations). So if I include function into 2 pieces of code and pass functions back and forth, they better have the same alignment! (And considering that boost.threads is typically compiled into a separate dll, and uses boost.function, it is not hard to run into the problem). I was working on a test and/or patch and/or etc to make sure I understand it correctly, but since function was brought up anyhow... Has this been seen yet? Do you think it is a boost issue, or a client issue? What do you think the best fix is? I think you could re-order the members (largest first), but that would still make arrays of functions suspect. Otherwise, should you be using the boost pre/post alignment headers? Tony
