Common malloc/free practice violates ANSI standard ?

[T. William Wells]

: * assigning a void* to an OBJ* involves rounding up to an even address

: * assigning an OBJ* to a void* involves no change of address

The standard requires that casting from (void*) to (OBJ*) and back
give pointers that compare equal and point to the same object.
Free will have no problems with it.
