Bug report #15738

Repeated segfault when merging and editing polygons

Added by Karl Kastner over 7 years ago. Updated over 6 years ago.

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.
The core dump is compressed 72MB and therefore not attached. I will provide the core dump on request.
