Bug report #15738
Repeated segfault when merging and editing polygons
|Affected QGIS version:||2.14.1||Regression?:||No|
|Operating System:||Ubuntu Linux||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:||not reproducable|
|Crashes QGIS or corrupts data:||Yes||Copied to github as #:||23660|
Steps to reproduce:
Open the attached shape file that contains a set of polygons.
Select two polygons.
Merge the polygons.
Select the node tool.
Select a vertex.
Delete the vertex.
Keep selecting and deleting vertices until Qgis crashes.
Crashes on my machine at every attempt, but sometimes more, sometimes less vertices have to be deleted.
The merge step seems to be necessary to reproduce the bug.
