Can you explain what you mean? Because I read the bug report and it seems to be some intricacy about loading variables into a register solved by using volatile. Meaning it's a complicated implementation detail of the CPU, and does not seem to be because they reinvented the wheel. Plus is there some standardized library they should have been using?
