  way to reproduce the bug in a 2GB c2d linux laptop (sony vaio fe31h)
  with lots of free space:

  1 - start scilab
  2 - In the scilab console, type:

  --> a  = 1:1:10000;
  --> b  = a';
  --> kron(a,b);

  ** CRASHED ** with the output pasted above.

  cat /proc/meminfo output (don't know if it's useful tho):
