I'm unable to reproduce this with the same build and runtime
configuration files that you listed. Where your log shows "Segmentation
fault", I see "nl80211: Event message available". Would you be able to
run hostapd under valgrind ("valgrind hostapd ...") to see if it gives
useful information on what is failing? Alternatively, run under gdb and
report backtrace output form gdb after the segmentation fault.
