I believe they are using GCC 10.2.0 as am I. I rebuilt the iwd-git AUR
with the addition of the suggested 'disable-optimization'. I installed
it and restarted the iwd service and get the same result with the
test-eapol:
...
TEST: EAPoL/FT-Using-PSK 4-Way Handshake
TEST: EAPoL/Supplicant+Authenticator 4-Way Handshake
test-eapol: unit/test-eapol.c:3698: eapol_ap_sta_handshake_test:
Assertion `s.ap
_success && s.sta_success' failed.
Aborted (core dumped)

**BUT** now that I an using the latest iwd-git without optimizations
and try to connect to it in AP mode, I connect. Also if I let connman
use it as a tether, I also connect. If I re-build iwd-git 'with
optimizations' and try again, it fails.

This is on an "Raspberry Pi Model B Plus Rev 1.2"
