Could you please try running hostapd under valgrind or gdb to get full
backtrace of functions at the time of the segmentation fault?

I've resolved the header file conflicts in the current development
version of hostapd by replacing '#include <linux/wireless>' with
'#include "wireless_copy.h"' in driver_nl80211.c. What made you
uncomment the USE_KERNEL_HEADERS definition?
