Rainer,

I don't see the crash on FreeBSD 10.0-RELEASE amd64 and 9.2-RELEASE
amd64 - those are versions I tried and where I could successfully open a
Sony ARW file and click a few UI items.  Note sure what 11 changed that
it would break.

It's rather that the base /usr/bin/gdb cannot deal with the newer debug
symbol formats...

...do you have more luck with gdb built from the ports collection
(devel/gdb), which is version 7.6.2, as opposed to the base system gdb
6.1.1?

Also, if you recompile rawtherapee without the highly aggressive
compiler flags, does that help?

I saw warnings about undefined behaviour in aggressive loop
optimization, not sure if those are the culprit.  If they are, we might
need to tune down optimization a bit.

Thanks.

Cheers,
Matthias
