This unfortunately seems pretty difficult to debug. One thing I could imagine doing is minimizing the problem, by first stripping everything away from `scipy.sparse` except the sparsetools module, and then stripping down the sparsetools code until the failing part is found.
Another possibility is that the problem comes just from the c++ runtime. There's another c++ module in Scipy, `scipy.interpolate._interpolate` -- could you check if importing it also causes the same issue? -- Pauli Virtanen
