    _______________________________________________________

Details:

In Octave devel (3.3.54+), the following crashes:

clear a;
a.field=single(1);
save a.mat a -v6;
load a.mat

returns:

error: load: invalid element type = 0
error: load: trouble reading binary file `a.mat'

while it works fine with current stable version (3.2.4).

It seems to be due to a bug with the handling of single precision variables.
