Comment(by pv):

 Looks like it's a problem in the iterative solvers. You can further try to
 confirm this by removing `aslinearoperator` from the `self.mattypes` list
 in `scipy/sparse/linalg/eigen/arpack/tests/test_arpack.py` on lines 208
 and 258, and running the `scipy.sparse.linalg.eigen` tests only.

 There *is* definitely something strange going on in the iterative solver
 sources, as shown by their spurious convergence failures with different
 compilers, so having also a real crash is probably not unexpected.
