Description
I have a problem with QGIS 2.6's Difference Geoprocessing feature. In my project, I have to cut hundreds or thousands of small vector polygons from a bigger polygon area, the small being trees and the big one a region. For some reason if the bigger polygon area is too massive the process seems to fail and create a dump file, which is the one as follows (about 27,7MB):

Is there any limit for this tool that makes it not even try to process the data?

Could you try with 2.12 or master and report back?

I've fixed the problem by using the Dissolve tool in the tree layer. If I use a dissolved layer, it processes properly. Which makes no sense to me, since it is still a massive ammount of minuscule polygons that are distant from each other, but it works, so all good.
Thanks for answering.
