Yes, sorry. In fact I was out by "one level of indirection" :)
The NULL I saw was actually correctly initialised fresh slot
in the array. Judy was working fine as usual.
Just FYI the bug was in my code generation. The data value
for this array is a list of stuff. I basically did:
insert "string" return slot
*slot = Prepend new-data to
get "string"
if NULL then Empty-List
else list-at-slot;
So the "get" always succeeded because it was done after the insert,
but it fetch a NULL instead of a list pointer.
