[Numpy-discussion] wired error message in scipy.sparse.eigen function: Segmentation fault

[Jankins]

I tried on Ubuntu 9.10-32bit, gcc version 4.4.1, . Here is the 
information of show_config():

In [2]: scipy.show_config()
umfpack_info:
   NOT AVAILABLE

atlas_threads_info:
   NOT AVAILABLE

blas_opt_info:
     libraries = ['f77blas', 'cblas', 'atlas']
     library_dirs = ['/usr/lib']
     define_macros = [('ATLAS_INFO', '"\\"3.6.0\\""')]
     language = c
     include_dirs = ['/usr/include']

atlas_blas_threads_info:
   NOT AVAILABLE

lapack_opt_info:
     libraries = ['lapack', 'f77blas', 'cblas', 'atlas']
     library_dirs = ['/usr/lib/atlas', '/usr/lib']
     define_macros = [('ATLAS_INFO', '"\\"3.6.0\\""')]
     language = f77
     include_dirs = ['/usr/include']

     library_dirs = ['/usr/lib/atlas', '/usr/lib']

Thanks so much.
