I may not have been clear enough here. My bug report was intended for
the debian binary package, not Gromacs itself. The binary package
cannot be "configured", it's already compiled, there is nothing you
can configure about it. Also, I'm not asking for support, I'm filing a
bug report. I can compile Gromacs from source, that is not the issue.
No, this bug is not fixed in #725013. I reported the bug for the
latest debian binary package, 4.6.5-1.
I guess the package maintainer should decide which processors the
binary package is intended to support. If only certain CPUs are
supported then this should be indicated in the package name or title.
Or if the purpose is to provide a generic version that will run on
most processors then it should not depend on AVX.
