Details:

When I am doing the following on my Gentoo system:

-------------------------
x = [1 2];
y = [2 2];
semilogy(x, y);
a = 1.1;
set(gca, "ylim",[a, 2])
-------------------------

a get this message:
  "error: memory exhausted or requested size too large for range of Octave's
index type -- trying to return to prompt"


Everything works fine as long as 'a' is less or equal to 1.0 (or more precise:
a <= 1+e-16).

I encountered this when using the function 'axis()'. Then, I digged through
the code of axis.m until I was at line 289...
    if (len > 3)
      set (ca, "ylim", [ax(3), ax(4)]);
    endif
...which results in the error mentioned above and crashes a running octave
program.
