SIGSEGV on IWD 3.2

Hi All,
Long shot here,
I was debugging a logs of a device from an SQA person that had
repeated IWD SIGSEGV and restarting probably after wifi driver went
out to lunch.  Somewhat limited logs since I didn't get to it right
away and stuff started to roll over.

Also interesting, did not even have any wifi in use either in station
or AP (Nothing had been provisioned).  This device had previously been
used for some wifi a week or 2 before, but all networks were cleared
out and device restarted.

We use s6-rc as our service manager.  If a process (such as IWD) dies
it will repeatedly try and restart it.

Had what looked like wifi driver having issues - probably the start of
the whole issue.

In some s6-rc logs, we have when it was restarted (continues on with
this and lost some info to rollover)

For IWD logs I have repeated restarts like this snipped log, but I
don't see an error. (I have the restarts from the same times as above
as well)

Anything useful I could get out of this? I was thinking of enabling
iwd debug logs to hopefully have some more information if we can repo
this issue.  Most likely it is on the driver side - we had been
fighting driver issues in the past...
