Dwipreproc error: Inconsistent left-right order stored in sform and qform

Thanks for doing all this. Clearly the issue remains, but I am completely stumped - I’ve just tried all combinations of strides I could think of to reproduce this error, nothing triggers it on my system…

The only differences between your installation and mine relate to the compiler version (I run g++ 5.3.0, you run g++ 4.8), and Eigen (I run 3.2.8, you run 3.2.0). There is a very slight possibility of a compiler bug in g++ 4.8, since C++11 was relatively fresh in that version. It may be worth trying to use a more up to date version from the Ubuntu Toolchain PPA - this should allow you to install g++ 5.3.0, on the off-chance this is the problem. To use this compiler, use something like:

$ CXX=g++-5.3 ./configure

Updating Eigen might also be an idea if that doesn’t resolve the problem - see recent instructions for this here.

Other than that, I’m all out of ideas… If anyone else can think of some reason for this, I’m open to suggestions…
