The attached polyhedron whose H-rep uses QuadraticExtension crashes polymake (segfault) when I try to compute the vertices.
This is with Polymake 3.1 on Mac OS X, compiled within Sage using the minimal tarball. Simpler calculations, including some with QuadraticExtension, seem to work fine with this build.

OK, this is a bug. Actually, it already crashes in 3.0. Stay tuned.

The reason is a zero vector among the INEQUALITIES. While we probably have a specification that explicitly forbids this, I agree that it is a bit drastic to die on a segfault. We will deal with this.

For now, you can work around by leaving out zero vectors.

Thank you, this workaround works. Code is at: https://trac.sagemath.org/ticket/22723
