Aiee, segfault! You should probably report this as a bug to the developer

I can't think of anything obviously wrong with that setup.
Is it possible to run gdb on the pc104 system to find out
where the segfault is occurring (let me know if you need a
hand)? If not, you could try compiling Dropbear with
DEBUG_TRACE enabled in debug.h and running dropbear with -v,
that should spit out some extra output about which function
it's crashing in. It might be worth trying with DSS keys
instead of RSA keys to help narrow it down.

Cheers,
