Description

With preview version of Wt4, github 3.3.6-22-gb3a1dd7b, a WCartesianChart with plain (area-based) tooltip frees areas twice.

This should be reproducible with a tool such as valgrind and the attached patch to examples/charts/ChartsExample.C. Modifying the Category Chart by disabling the "Rural Male" category causes a segfault in my environment.

A lightly test patch is also attached for your review.

It looks like this issue may have been resolved with github 3.3.6-25-g08b73ba (just based on presence of patch). Thanks!
