3.19b Crashing - Illegal instruction (core dumped)

At least since 3.19b, a clean install (Debian Stretch in Docker) will crash at startup.

Start a built image in bash:

> docker exec --rm -it bbsio/synchronet:3.19b bash

Run the sbbs-init to ensure the node directories etc are extracted (note, also downloads x00, but unrelated).

Run sbbs, will start, and summarily crash.

Will attempt to gather a GDB capture and attach additional details... logs below.
