In a handful of cases, it was decided to return a pointer to a
structure rather than the plain structure itself, due to the size.
However, in these cases the structure was never allocated, leading to
a nil pointer exception when calling the relevant `fromC` method.
Allocate structures before attempting to fill them in.

This has been compile-tested only; Tobias, I'd appreciate a test if you get a chance.
