Problem concatenating structures.

[David Bateman]

I have little time to look at this at the moment, but wanted to document 
an issue I'm having with structure concatenation. Consider the code

s = warning("query","Octave:imag-to-real")
[s, s]
[warning("query","Octave:imag-to-real"), 
warning("query","Octave:imag-to-real")]
[s, warning("query","Octave:imag-to-real")]
[warning("query","Octave:imag-to-real"),s]

With a build from the hg tip I see

octave:1> s = warning("query","Octave:imag-to-real")
s =
{
  identifier = Octave:imag-to-real
  state = off
}

octave:2> [s, s]
ans =
{
  1x2 struct array containing the fields:

    identifier
    state
}

octave:3> [warning("query","Octave:imag-to-real"), 
warning("query","Octave:imag-to-real")]
error: invalid row index = 121
error: caught execution error in library function
octave:3> [s, warning("query","Octave:imag-to-real")]
error: invalid row index = 121
error: caught execution error in library function
octave:3> [warning("query","Octave:imag-to-real"), s]
error: invalid row index = 121
error: caught execution error in library function

I see no reason for this difference, and valgrind doesn't report and 
error, but its stopping me implementing the intwarning function.. Any 
ideas of the cause?
