Better would be to change the object representation so that the header of objects would be always 64 bits (or better, split into a 32 bit length and 32 bit type and GC flags). The implementation complexity of both is about the same (roughly 2 days of work). However, too much work for me right now given the low need for this feature.

Mind you, if I used WIndows, I would have had to trow the machine out
