hello,
code below:
-----
class a {
string a1;
}
a a1;
writeln(a1.a1);

compiles and produce "core dump" or "segfault", does this fit
the original D design? why the compiler does not detect for
accessing a null object and refused to compile?
And, 2nd question: where can I find the Subset spec of SafeD?
Thanks!

Yes this is by design. It is not easy to detect this at compile
time.
It does not break safety
