You did not show us the SQL definition of the type. I don't see anything
obviously wrong in what you showed (other than hfsize_add not setting the
result's scaling), so the problem is somewhere else. Given this C
declaration, the type probably needs to be size 16, double alignment,
pass-by-reference; maybe you messed up part of that?

What is new_HFSize?
