Package: mosquitto
Version: 1.4.10-3+deb9u3
Severity: grave
Justification: renders package unusable
Dear Maintainer,
* What led up to the situation?
On armv7l box, after updating from 1.4.10-3+deb9u2 to 1.4.10-3+deb9u3,
mosquitto dumps core on startup.
Used gdb to get a stack trace (after installing mosquitto-dbg):
(gdb) bt

(Please excuse the linewrapping. I've edited the arguments on frame #2
to remove actual user and device name; please feel free to comment on
the report if you feel the actual strings are relevant)
* What exactly did you do (or not do) that was effective (or
ineffective)?
Downgraded to older version 1.4.10-3+deb9u2, which works. I
haven't attempted any debugging with the latest version because I
am not sufficiently clueful.
