Description

When use the "Control feature rendering order" in QGIS 2.18 on mac OSX sierra, it will be crashed.

Reproduce:
1. Add the csv file as a layer, ( with header, wgs 84)
2. In the Layer style dialog, check the "Control feature rendering order", define the order express, choose "count"
3. Click the Apply or OK button

I have tried:
1. Convert the csv file to shape file, crashed.
2. Sort the csv file with count column, crashed.
3. Decrease some lines of the csv file (about ~500 lines, total 30.5K lines), not crashed. Maybe memory problems?

#5 Updated by Martin Koppenhöfer about 7 years ago

I can confirm this bug (crashing when "control feature rendering order" is activated) also for Mac OS High Sierra (10.13.1) and both, QGIS 2.14.20-1 and QGIS 2.18.14-1 (both are current releases from kyngchaos). I also suppose it is a memory issue, because it doesn't happen (so far) when zoomed in (few features visible).
