Description

In the notes of nalgebra v. 31 and lapack v.22 it states improved behavior when dealing with the computation of eigenvalue problem.
While I can confirm this for nalgebra, the lapack variant still crashes.

This works: `action_matrix.complex_eigenvalues()`
This crashes: ` nalgebra_lapack::Eigen::complex_eigenvalues(action_matrix)`

The lapack integration works since I use it use compute SVD etc.

The error is
```
** On entry to DGEEV parameter number 1 had an illegal value
The application panicked (crashed).
Message: Lapack error.
Location: /home/marc/.cargo/registry/src/github.com-1ecc6299db9ec823/nalgebra-lapack-0.22.0/src/eigen.rs:272
```

Tested on Ubuntu 20.04 (WSL)
