That was helpful in tracking down the bug, which Matt and I have now fixed here: https://git.zx2c4.com/wireguard-freebsd/commit/?id=c69fb61b94341027ea3c539bcf96d9fe03f65fa5 The commit message includes a little bash reproducer that hit the same crash in my tests, making me somewhat confident we squashed the right one.
