Details:

This problem happens for int64 and uint64 types on Octave 7:


octave:16> lo = uint64(10) ^ 17      
lo = 100000000000000000
octave:17> hi = lo + 1e3
hi = 100000000000001000
octave:18> class(lo)
ans = uint64
octave:19> class(hi)
ans = uint64
octave:20> lo < intmax ("uint64")
ans = 1
octave:21> hi < intmax ("uint64")
ans = 1
octave:22> rng = (lo:hi)
error: colon operator upper bound invalid (not an integer or out of range for
given integer type)


The values lo and hi are within the legal range for int64 and uint64 but the
colon operator fails when trying to create what should be a valid range.
