majorGridLineStyle]: message sent to deallocated instance 0x3d550a0

What is the expected output? What do you see instead?

it seems that after the last cleanup to fix the memory cycle, some objects
are over-realeased... My own app breaks on same object  (CPXY axis).

What version of the product are you using? On what operating system?

rev 745

Please provide any additional information below.

The extra layers for the grid lines aren't being removed along with the axis 
set. When the system tries to redraw 
the plot after a rotation, the grid line layers try to access properties from 
axis objects that no longer exist.

I'll take a crack at fixing it.

I encountered the same issue and fixed it by modifying CPAxis.m. I added
label.axis = nil; /* as line 694 */
axisTitle.axis = nil; /* as line 736 */
minorGridLines.axis = nil; /* as line 1030 */
majorGridLines.axis = nil; /* as line 1044 */
