Also, generally, wouldn't it be more correct to call SymFromAddr from
SymFromAddr64 and not vice versa? Ie forward from more limited to less
limited functions, and not from less limited to more limited functions
(the limitation being here that SymFromAddr() only supports 32 bit
addresses etc, while SymFromAddr64() also supports 64 bit ones).
