#288 qfcc segfault
While I have no problem building quakeforge-0.7.0 on FreeBSD, qfcc crashes trying to build quakeforge-0.7.2 and quakeforge-0.7.1a.

Please ask me if you need any other info or test.
I believe this is fixed in git. A patch for fixing emit_ivars is the first patch to qfcc after 0.7.2 was released. Please get the latest and let me know if it's fixed.
The problem went away after patching 0.7.2 with
https://sourceforge.net/p/quake/quakeforge/ci/6a3c775270701d3672461f143b6632484e5f32fa/
https://sourceforge.net/p/quake/quakeforge/ci/9d418379bfd515a1707742b4d3d295e47846fc8f/
and then, after switching to gcc-4.7 from the one in base, with
https://sourceforge.net/p/quake/quakeforge/ci/7137783e47ad97f2a1352fe34b876015f4dfd1a8/
I'm not sure that just the first patch (+ maybe gcc-4.7) is enough, I should make another test.
In the meanwhile, and waiting for a new release ;), thank you very much for your fast reply and suggestion.

BTW, it seems that keybindings are buggy in 0.7.2 compared to 0.7.0.
In 0.7.0 I have K_w to walk forward but in 0.7.2 is not working.

Any idea about what could be the problem?
It's the same for 0.7.1.
Why not just get the latest git version? Many more bug fixes and some nice new features.
However, yeah, I do need to do another release sometime.
