 Hi, some matrix will cause python process crash when call sparse solver
 spsolve() and print "Illegal instruction (core dumped)".

 I have dumped the matrix by pickle and write a simplified script(10 Lines)
 to show the bug.

 My environment: Intel P4 CPU (64B)
 Linux 3.2.0-40-generic #64-Ubuntu SMP x86_64 GNU/Linux
 Python 3.2.3, Numpy 1.7, Scipy 0.12
