Hello,

I think I've found a bug. Maybe this is not expected to work yet
but anyway here is my (short) report:

There is a problem with indexing the left side of an assignment.
An example (0.79):

	octave:2> x(7:-2:3)=[1 2 3]
	x =

	  0  0  3  0  2  0  1

works only if x is previously initialized with say x=zeros(1,7) and
otherwise produces a

	octave:1> x(7:-2:3)=[1 2 3]
	panic: impossible state reached in file `tc-assign.cc' at line 414
	error: caught SIGILL -- stopping myself...

Quite interesting in 0.76 this was

        octave:1> x(7:-2:3)=[1 2 3]
        panic: impossible state reached in file `tc-assign.cc' at line 391
        error: caught SIGIOT -- stopping myself...

PS. I think Kurt Hornik sent you some of our m-files for evaluation but
    has got no confirmation that you received them. Did you ?
