hi. mingw's g++ 3.4.5 (i think, the most recent one) gives

when i do g++ -O2 -fomit-frame-pointer de.cpp -ode, and doesnt print 9. that's
kind of ok.

when i do dmc de.cpp -o -6 -cpp, or dmc de.cpp -o -6 -cpp -Aa it gives nothing.

is there a problem with dmc in this case, or is it related to some other thing?

The program is not well-formed.

The behaviour of

     p = new A(9);
     delete[] p;

is undefined. So any compiler can "legally" do anything it likes with your
"illegal" code.
