Hi,
I'm a maintainer of Rawtherapee packages. I'm using Open Build Service
(https://build.opensuse.org/package/show/home:rawtherapee/rawtherapee)
I have a problem with build the project for Fedora 24 (i686 + msse2) (gcc
6.1.1) with standard set of CXX flags recommended for building packages on OBS:

-O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions
-fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches
-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m32 -march=i686 -mtune=atom
-fasynchronous-unwind-tables

+ flag added by me: -msse2

Build finished with "internal compiler error: Segmentation fault"

There is no problem with build for Fedora 23 (gcc 5.1.1) where the same flags
are used.

I've noticed too that there is no problem if I remove -mtune=atom.

To build the project locally use Open Build Service commander:
$ osc co home:rawtherapee rawtherapee
$ cd home\:rawtherapee/rawtherapee/
(optional) modify rawherapee.spec file
$ osc build  --no-verify Fedora_24 i586 rawtherapee.spec --clean
