How was your perl compiled?: perl -V:ivsize

It could well be that this has nothing to do with Judy but that for your Perl, 1<<63 overflows and becomes negative which Judy then receives it and complains.

Also, from Judy source, Set() accepts a key as UWord_t which is T_UWORD which is:

T_UWORD
    /* Accept:
       - IV that's -1.
       - IV that's negative, coerce to 0 and warn.
       - IV/UV that fits in (unsigned long int)
       - IV/UV that requires more bits than fit in (unsigned long
         int). Truncate it and throw a warning.
       - Cast everything else to UV and apply the above rules
     */
     ...

edit: IV: integer value, UV: unsigned valued. In my system with ivsize=8, perl -e 'print 1<<63' outputs 9223372036854775808, do you get the same?
