It looks like I'm unable to reproduce this. Would it be possible for you
to use gdb or valgrind to get a backtrace or at least the location of
the segmentation fault?

By the way, this is invalid configuration. With ap_scan=2, only one
option for proto/key_mgmt/pairwise/group is allowed. Not that this
should cause the crash (and it did not in my tests), but it may result
in unexpected results.
