Have it print the pointer 'a' as a %d using rtl_printf. See if 'a' is even
being assigned an address.
Do it like this:
AbstractBaseClass *a;
a = new AbstractBaseClass();
rtl_printf("%d\n",a);
That'll tell you if a is even being set. If so, delete should frankly work.
I didn't realize you were trying to do cpp inside RTL. I forgot what list I
was on, heh. I haven't ever had a need to do CPP inside RTL so I can't help
beyond that. That's why I suggest seeing if a is even assigned, since maybe
that'll tell you if the new operator is working correctly.
