From the Judy Arrays web page:

The Judy family of functions supports fully dynamic arrays. These arrays may be indexed by a 32- or 64-bit word (depending on processor word size), a null terminated string or an array-of-bytes plus length. A dynamic array (sparsely populated) can also be thought of as a mapping function or associative memory.

A Word_t is a typedef unsigned long int in Judy.h and must be the same size as sizeof(void *) I.E. a pointer.

unsigned long int is a 4-byte integer on 64-bit Windows.

This seems to be the 64-bit data model difference between Windows (LLP64) and *nix (LP64) raising its ugly head.

Word_t should be typedef'd as long long in order to ensure that sizeof(Word_t) == sizeof(void*) on both platforms.
