On a Raspberry Pi 1B (using the community kernel, mkfs segfaults consistently for me.
Debugging this through breakglass+busybox, I found the mke2fs binary shipped with mkfs doesn't work:

Segmentation fault
Trying another pre-built mke2fs binary for arm, this is the result:

This is the diff that file shows:

I tried switching from armhf to armel and it now works for me (notice how it changed to SYSV, when I switched to armel):
