 Have been seeing segfaults with the most recent version of the channel
 scanner. I'm usually starting the full scan by tuning to 10773000kHz, with
 and without encryption testing enabled.

 Attached are the gdb traces of what seems to be 4 segfaults. I have been
 having problems triggering the segfault consistently, and in my experience
 the segfault was most observed when running a release build (so most
 unhelpful for debugging). Debug builds seemed better in my limited
 testing, profile builds seemed prone to hang during scanning.

 The issue seems to lie in ChannelScanSM::UpdateChannelInfo(bool).

 Apologies if these backtraces are not helpful (I am new to gdb). I will
 continue to try to get a debug build to segfault a few more times to be
 helpful.
