Yes Virginia, you can enable alignment exceptions on x64

I received the feedback forms from the Paris event a while back and noticed the comments from Gilles Vollant in which he suggested we touched a bit more on the 64-bit alignment issues. After exchanging mails back and forth a bit, it seems that it is possible enable x64 exceptions on an x64 machines (by default, these machines handle the exceptions in-hardware and only suffer a performance hit). Why on Earth would you like to change this? Well, if you are a developer writing software for 64-bit systems and would like to rid your software of alignment faults, it would be quite difficult to do so without knowing where/when they occur. Here is an excellent article Gilles Vollant wrote about alignment on both architectures: I have not yet tested this and once I get my hands on some machines next week at the Canada event next week, I’ll investigate some more and post any issues I may find.
