You never called the constructor, which means it was lazy

So when it set its internal pointer, it was inside a function and
never got seen outside. Similar to if you do
char* a;
void foo(char* a) {
a = new char[](10);
}
foo(a);
If you were to put something before the other calls, it would
work. Or call the constructor (which the little-a appender
function does).
I'm kinda of the opinion this should be a compile error; that it
should force you to call the constructor, so that could be a
minor bug, but it isn't unexpected per se since regular pointers
and arrays work the same way.
