 Hi, thank you for reply,

 Output from script is:
 .cpython-32mu.so: mmx pentium_pro sse sse2

 The spsolve can solve small matrix successfully, but crash Python when
 solve large matrix. And I used pre-built scipy/numpy on Ubuntu 12.04, so
 it should be compatible binary. After encounter the crash problem, I
 download latest scipy/numpy from sourceforge and configure/make install,
 the problem remains as before.
