This needs to be initialized to NULL, otherwise you may end up freeing a
random memory if the control jumps to 'error' label.

What are you missing here is fs = NULL; after the insert. Otherwise in
next iteration - if we fail - we jump to 'error' and free @fs which,
however, is already part of domain @def. Same applies for @disk.
Previously it wasn't problem as there was only @disk which would get
overwritten as the first thing in new loop.
