Details

3D models (binary cmod files) of some objects (for example ISS, Phobos, Deimos, etc.) aren't displayed in Celestia. This is caused by GCC 4.1.x. There is patch from https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=203525 which should fix this problem. I have tried it and it works on some models (Phobos, Deimos, etc.), but doesn't fix spacecraft models (ISS, Hubble, etc. is still not displayed). Maybe problem with spacecraft models isn'ŧ related to this "strict aliasing" bug.

I have added this patch to official Celestia PKGBUILD and also modified it to avoid this bug: http://bbs.archlinux.org/viewtopic.php?t=23373
   PKGBUILD (1.2 KiB)
   celestia-1.4.1-strictalias.pa... (0.4 KiB)
This task depends upon

I can confirm this bug in package version 1.4.1-3

Can you test this with 1.5.0, it might (hopefully should) be fixed.

Just tested it myself, didn't think I had the models, but apparently I do. Phobos, ISS, Hubble are showing fine here.
