Octave's oct-modules built with gcc-3.4.4-1 crash octave.

The last time I checked, Octave just doesn't work with gcc 3.4 on
Cygwin systems.  I think the biggest problem is this bug

  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24196

which was also discussed in this thread:

  http://cygwin.com/ml/cygwin/2006-01/msg00297.html

and there also seems to be a related problem here:

  http://cygwin.com/ml/cygwin/2006-01/msg00495.html

though I'm not sure that these two problems are precisely the same
bug.

If you are using the binary package from a Cygwin mirror, then I think
you will have to use gcc 3.3 to built .oct files.   I'm fairly certain
that the binary package of Octave is built with gcc 3.3, and it is
best to not mix C++ compiler versions when building .oct files.
