python script crashes QGIS

[qgib]

Original Redmine Issue: 20261
Affected QGIS version: 2.18.17
Redmine category:pyqgis_console

I have written a python script which has two input vector layers (one point-layer and one line-layer). The outpout is another line-layer. But when I try too set the geometry for the new edge, the python script stopps and I get the error "minidump written to C".

Here is my python script code:

https://gis.stackexchange.com/questions/300562/qgis-python-script-crashed-with-minidump-written-to-c

With the help of printf-Debugging, I have figured out that the crash is caused by this line:

-> newEdge.setGeometry(QgsGeometry.fromPolyline([geomFrom.asPoint(),geomTo.asPoint()]))

I have already deleted the .qgis2-folder and started qgis 2.18 anew. But without success.

Any suggestions?

This is fixed in QGIS 3.0

In 2.x it's necessary to make an explicit copy of all geometries you capture from features, e.g.

geomFrom = QgsGeometry(feat2.geometry())
