Created attachment 113517 [details] typecheck Matrix.__mul__ second operand In python3-cairo, the routine that implements the “*” operator between two Matrix objects neglects to ensure that its second operand really is a Matrix. Pass an arbitrary value, and it will cheerfully return nonsensical results, possibly even accessing invalid memory and causing a crash. The enclosed patch adds the necessary typecheck.
