--- Comment #7 from eyenseo at gmail dot com --- (In reply to Jonathan Wakely from comment #6) Thanks for letting me know of the "importance-ignoring" one two less clicks next time ;) I didn't include the segfault in the precompiled file as I would not be able to get the full output that describes the bug better than the segfault. So in the end we have to assume that the travis setup and my system get the error because the Ubuntu guys build gcc wrong - but not recognisable in the build settings I included in comment #1 ?
