In this particular case, the segmentation fault in hostapd is caused by
the kernel.  There are some places in the kernel where it delivers
SIGSEGV to the current process.

The primary problem is an "oops" in the kernel.  Oops is a malfunction
of the kernel that doesn't stop the OS.  The segmentation fault in
hostapd is a side effect.
