Hi, I investigated the segfault issue in kallisto, and found a fix for it. Details can be found at https://github.com/pachterlab/kallisto/issues/254#issuecomment-629546051
I've written a patch to avoid the segfault, for the time being, until upstream fixes it. Please take a look. https://salsa.debian.org/med-team/kallisto Regards, Pranav ᐧ
