Thanks for the kind words. We have been making good progress on fixing
these types of problems. Eric Hovland and Stuart Morgan also deserve
mention as active bug squashers. The effort to squash these types
of bugs began a few years ago when Eric Hovland started running
Coverity on the source and producing bug fixes. Since then Stuart and
Beirdo got automated cppchecks running and Coverity has given us free
access to their scans of our code (after Eric Sharkey contacted them
on our behalf). I added the icc and clang coverage since these compilers
also detect some problems gcc misses.

It can be a bit of a slog but for every 20 or so of the static
analysis detected problems addressed a user visible bug is fixed.
For the amount of effort expended that is a pretty good ROI.

BTW Your efforts to get us ready for Qt5 are appreciated. I have
every hope that transition will be a considerably smoother than
the transition to Qt4 was.
