The " intersection " module of processing plugin doesn't work properly .
In attached example intersecting the layer "B" with the layer "A" doesn't return any feature while intersecting the layer "A" with the layer "B" is properly returned a feature .
The cause of this bug is the " break " statement at line 106 of the "processing\algs\qgis\Intersection.py" file that prevents the evaluation of the successive intersections . Removing that line the algorithm works correctly.
The implemented algorithm in ftool plugin has a different structure and functioning properly (see lines 961 to 988 in fTools\tools\doGeoprocessing.py ).

It is not a bug, if intersection result has invalid geometry it skipped.

• tag was changed from processing, intersection to
• status_id was changed from Open to Feedback

Invalid geometry is skipped but the break line interrupts entire cicle and other geometries that overlap first geometry and produce valid intersections don't be evaluated.
In the attached example intersection result changes if input layers are inverted.
