To me, the fact that it always reads a longint regardless of the size of the property seems to be inherently wrong. What if the last field of a class is a byte? Then you can read past the end of the class, possibly into unallocated memory causing a crash, no?
No. Classes are always allocated on the heap so the memory block is always at least a multiple of 4.
So? What if the last field is a byte and is stored in the last byte of the e.g. 100 bytes that the class occupies? Keep in mind that getordprop does not necessarily read from a 4-byte aligned address. It simply reads 4 bytes from the start address of the field, and then ands the result with $ff if the size of the field was 1 byte.
Ops :) It seems I worked too much with my sparc ;)
