Segfault when indexing with high k

[Jakob Nissen]

Here’s an example

ngs85out/test/nscat via C base ❯ kma index -k 40 -i nscat.fna -o nscat
# Indexing databases.
# Updating DBs
# Reading inputfile:    nscat.fna
zsh: segmentation fault  kma index -k 40 -i nscat.fna -o nscat

I don’t know if there are any reason it segfaults when k > 31 - perhaps the kmers are stored in signed 64 bit integers. Anyway, an error message would be much appreciated instead of a segfault :)

I forgot to add it, thanks for the heads up. An error message has been added.
