Nice to see another person appreciate my desire to avoid those bugs as much as possible. Eventually I hope to see D avoid all four of them.
There are other bugs too, like ones derived by out-of-bounds pointer arithmetic, but they are less common (Cyclone and other languages are able to avoid them too, but it costs some).

Do you remember the ptr==null thing? As soon as D2 has full integral overflow checks, all people will find several bugs in their "large" D2 programs. I have seen this many times, switching on such overflow checks in Delphi programs :-)
