Dear list,

I've written a bignum fuzzer that compares the results of mathematical
operations (addtion, subtraction, multiplication, ...) across multiple
bignum libraries.


Hi there,

Is this fuzzer freely available?  I'd love to try it out on the bignum
support I added to the CHICKEN Scheme implementation for its upcoming
new major release (probably somewhere mid-2018).  Being able to release
it with a bit higher confidence in its correctness would be nice, as this
is almost all brand new code.

Cheers,
Peter Bex (CHICKEN core maintainer)
