Details:



I have recently upgraded my Octave 3.8.1 to Octave 4.0.0. i have been facing
the problem of this crash earlier in 3.8.1 also, some forum suggested to
upgrade, so I did and still the same.

When i was using 3.8.1, even a small plot made the octave crash and exit with
following error,

input: octave 1> plot(1:4,2:5);

result: panic : Segmentation Fault -- stopping myself --

Now in Octave 4.0.0

When i use the same plot function it prints

octave exited with signal 11

Please Help me! Thanks in advance.
