[QGIS-Developer] QgsRasterMarkerSymbolLayer

[beketata]

Hi all,

I am working on some modification to the Raster Image Marker class
QgsRasterMarkerSymbolLayer.
In the process I noticed some strange behavior of the original class.

I created a new test project with a layer containing a single Raster Image
Marker.
In the source file gqsmarkersymbollayer.cpp I added a global variable for a
QgsRasterMarkerSymbolLayer class instance counter. It increases in the
constructor and decreases in the destructor of this class.
Ideally (in my opinion) this counter should always be balanced. But when I
close and open the project again (with no extra action) the counter is
incremented by 3 each time in the iteration.
If I do something after opening the project, for example, changing the size
of the image, and then after closing and opening the project again, the
counter increases by 8 or more.
Almost the same behavior with the QgsSvgMarkerSymbolLayer class.

Is it some sort of leak or something else (normal)? Does this behavior
require further investigation?
