Several crash cases for build with recent sources

[Tatsuro MATSUOKA]

Hello

I have not yet tested recent development branch of sources.
I am now testing the latest octave-forge package on 3.0.5.

The test for development branch will be done after octave-forge package tests will be finished.

Regards

Tatsuro
