Release: stable branch, revision 5bf8af73fc34 of 01/06/2011 17:53

Description: Function handles save()ed with "-binary" can't always be
re-load()ed.

Repeat by:

octave:1> a = @ sin
a = @sin
octave:2> save ("-binary", "testdata.dat", "a")
octave:3> clear a
octave:4> load ("testdata.dat")
octave:5> a
error: `a' undefined near line 5 column 1

Note that it also doesn't work if the handle is a structure field:

octave:5> a.b = @ sin
a =

  scalar structure containing the fields:

    b = @sin

octave:6> save ("-binary", "testdata.dat", "a")
octave:7> clear a
octave:8> load ("testdata.dat")
octave:9> a
error: `a' undefined near line 9 column 1

But it does work if there is a different structure field (no handle) present:

octave:9> a.b = @ sin
a =

  scalar structure containing the fields:

    b = @sin

octave:10> a.c = 1
a =

  scalar structure containing the fields:

    b = @sin
    c =  1

octave:11> save ("-binary", "testdata.dat", "a")
octave:12> clear a
octave:13> load ("testdata.dat")
octave:14> a
a =

  scalar structure containing the fields:

    b = @sin
    c =  1
