I meant the example as an answer to your statement, "I wonder
how new memory is allocated without an explicit malloc here".
The postblit was intended as a chance to "fixup" everything
when you needed a deep copy. The new struct is initialized as
a shallow copy, so when you enter into the postblit, the
pointer is already pointing at the original location. Without
assigning it a new malloc'ed address, your memcpy was
essentially overwriting the original location with its own
data.
What I need was a deep copy, and I thought I could have done it
using postblit constructor. Thanks for clarification.
I think copy constructor is less confusing though.
