Definitely seems to be an issue with negative indexing. We are working on a
fix, sorry about that

Hey,
I encountered a segfault after adding a specific type of linear constraint
in cvxpy. While the backtrace (see here
https://gist.github.com/nkoep/486de1cdd8237d3fa9ed45919d5e1181) points
to one of Eigen's template methods, I figured it was most likely an issue
in CVXcanon/cvxopt/cvxpy given the maturity of Eigen. Of course, that's
just a guess and the issue could be caused elsewhere. Always hard to tell
when it comes to segfaults.A minimal working example can be found here
https://gist.github.com/nkoep/ed361820ba473e7ef85e1c9d8e857463. Here's
what python/cvx* versions I'm using:[numberwang ⚡ ~] » python -V
Python 3.5.1
[numberwang ⚡ ~] » pip list | grep -i cvx
CVXcanon (0.0.23.4)
cvxopt (1.1.8)
cvxpy (0.4.0)Some background on the problem: I'm trying to solve the basis pursuit
problem on complex data with the additional constraint that the solution by
conjugate symmetric so that its inverse Fourier transform be real-valued.Regards
