Comment(by pv):

 Hmm, I'm wrong about `.copy()` or saving/loading to a file fixing it. The
 bug appears also from reading the saved `.mtx` file -- it does not always
 result to a segmentation fault, but Valgrind sees it. The offending file
 is attached for later reference...
 import scipy.sparse.linalg
 import scipy.io

 CMC = scipy.io.mmread("CMC.mtx")
 CMCinv = scipy.sparse.linalg.spilu(CMC.tocsc())
