[SciPy-dev] ARPACK_gen_eigs

Hi all,

The attached script yields

python -i eigs1.py
Use minimum degree ordering on A'+A.
*** glibc detected *** free(): invalid next size (fast):
0x0000000000da8bf0 ***
Abort

Can someone reproduce this behaviour ?

If I change

sigma=1

to

sigma=1.0

it works fine.

And, why is the shift restricted to real values ?

Nils
