Ctrl-C crashes the application

[Giuliano Casale]

Bug report for Octave 3.0.3 configured for i686-pc-msdosmsvc

Description:
-----------

When Octave does time consuming tasks there is sometimes the need of
breaking with Ctrl-C. It is very painful that it then often crashes as
well loosing previous data&work in memory.

Repeat-By:
---------

1) Launch str = textread("longfile.txt","%s");
2) During execiton type CTRL-C to stop and everything crashes and closes.


Fix:
---

N/A
