Hi,

I cannot resolve the problem with symeig.test.test() with respect to the 
symeig package.
http://mdp-toolkit.sourceforge.net/symeig.html

A back trace yields

(no debugging symbols found)...>>> symeig.test.test()
Random Seed:  (1268049219, 2102953867)

Any idea what is erroneous here ?

Can someone reproduce the segmentation fault ?
