Could you run FR like this to trace it maybe?

./configure --enable-developer
make
make install
gdb /usr/local/sbin/radiusd
set logging file radiusd.log
set logging on
handle SIGHUP nostop
break modules/rlm_eap/types/rlm_eap_tls/rlm_eap_tls.c:323
run -f
# wait for it to crash
thread apply all bt full
print conf
print conf->certificate_file
