Description
SRFI 4 has four sizes of integer vectors, 8-bit, 16-bit, 32-bit, and 64-bit vectors in signed and unsigned flavors. Currently, there is no support for 64-bit vectors anywhere in Chicken 4, even if the numbers egg is loaded. With native bignums, supporting s64vectors and u64vectors is straightforward and should be provided.

I don't know what you've checked, but it seems to work just fine:
