Details:

The following code sequence

bar ( [0:10], rand(11,2) )
plotyy ( [0,1], [1,0], [0,1], [0,1] )
bar ( [0:10], rand(11,2) )

produces an error condition and leaves the plotting system in a seriously
damaged state.

The first call to "bar" demonstrates the system worked properly.
"plotyy" also produces a correct plot.
Further attempts to use "bar" fail with the following error messages:


octave:1> bar( [0:10], rand(11,2))
octave:2> plotyy ( [0,1], [1,0], [0,1], [0,1])
octave:3> bar( [0:10], rand(11,2))
error: invalid conversion from real matrix to real scalar
error: __calc_dimensions__: expecting graphics handle as only argument
error: called from:
error:

This error occurs on version 3.6.4 and Mac OSX 10.8.5, compiled with
Homebrew,
and also occurs on Ubuntu 12.04 LTS, downloaded from the gnu/octave site and
compiled with ./configure; make.

The error does NOT occur on octave 3.2 as distributed by the Ubuntu package
manager.
