legend.m has been rewritten (for OpenGL toolkits only). This bug should now be fixed.

Marking ready for test.

This bug is still present in the current dev 4.3.0 (39f39eb4e476).

I filed task #14243 about rewriting legend.m

The problem is that the legend object has text objects underneath it as well as having a fontsize property.  When the fontsize is changed on the underlying text objects the legend axes object is destroyed and re-created.  See bug #41142.  This causes an error when the set() function tries to address the non-existent legend object.

Sample code:

graphics_toolkit fltk;
plot (1:10);
legend ("abc");
fh = findall (gcf, "-property", "fontsize");
set (fh, "fontsize", 20);
error: set: invalid handle (= -29.205)
