GEOS exceptions crash QGIS on windows

[qgib]

Author Name: Anita Graser (@anitagraser)
Original Redmine Issue: 14752
Affected QGIS version: 3.0.0
Redmine category:labelling

---

The same project that works fine in qgis-dev and qgis-rel-dev (tested on Windows) crashes qgis 2.14.2. The dump file is attached.

It also used to crash 2.14.1 while the then qgis-rel-dev version worked. Therefore, back then, I assumed the issue had been fixed ... but it seems to be much more mysterious.

I can't reproduce (using Linux)

Another user reported the issue to me, so it's not a local issue on my machine. Maybe Win-specific.

This is what I see on Windows:

• seems ok up to 2.12 (tested 2.8, 2.10 and 2.12)
• 2.14.3, project opens, no crash, empty canvas
• master, project opens, no crash, map cannot be zoomed or panned.

weird, tested again and is ok on master (still not ok on 2.14.3, but no crash also).

The crash seems gone in 2.14.3 (OSGeo4W version). The project even shows up correctly on canvas (not empty as Giovanni mentioned).

In master, the canvas appeared empty when I first tried opening it. Used "zoom to extent" and it displayed fine. When I closed and reopenend again, everything looked ok from the beginning.

Bit strange ... Will reopen if crashes reoccur.

The issue seems to have resurfaced in 2.16.1-2, causing crashes and the attached minidump (provided by K Trinko).

I can confirm the crash on loading in 2.16.3 (build #7d00cae). But the project opens fine in QGIS 2.x master (2.17, build #6e4dbc0)

However, even with 2.17, if one zooms in, rendering can be very slow. Maybe an issue with the glow/shade effects when zooming in? But that is a different issue ... Also there seem to be projection/clipping issues when zooming around ? Definitely something weird in this project.

I tested on Win 7 with the Win64 builds.

I've narrowed it down to the point city layer. When 2.14 tries to render that layer, it crashes.

There is a GEOS Exception: IllegalArgumentException: RobustDeterminant encountered non-finite numbers.

I've further narrowed it down to activating "Discourage labels from covering features" for the city labels. If this is deactivated, the crashing stops.

Anita for sake of clarity would you agree if I then create a new issue ticket with just this fundamental piece of information (and the necessary dataset)?

Hi Anita,
made some test of my own.

2.14.15 crashes on project load, as well as 2.18.9.

2.18.9 nightly does not crash on project load.

BUT

I tried load the point layer in 2.18.9 nightly in a blank project, enable labels without the "Discourage labels from covering features" option and if you zoom in/out quickly with the mouse wheel is easy enough to make it crashes too...

all from osgeo4w.

this was before "I tried load the point layer in 2.18.9 nightly in a blank project, enable labels without the "Discourage labels from covering features" option and if you zoom in/out quickly with the mouse wheel is easy enough to make it crashes too..." :)

if the source of the problem was 100% that option would had made sense to create a new simpler and clearer ticket, as it does not seems the case I think that is better to keep the ticket as it is.

Tried again on master... and here with MT enabled it seems to not crash... what about others?

2.14.19 and 2.18.13 crash for me.

2.99 does not crash, but the project CRS and some layer CRS are not restored correctly :(

Seems like I don't have any version that opens the project correctly anymore.

2.99 does not crash, but the project CRS and some layer CRS are not restored correctly :(

but this could be another issue. I set manually the project CRS to 3857 and it works/shows fine for me, what about there?

[qgib]

Author Name: Anita Graser (@anitagraser)

---

Yes, I can set the correct CRS manually, and so far 2.99 doesn't seem to crash ... but we've observed this behavior with previous master versions as well.

Master currently doesn't crash but - considering the history of this bug - I'll only believe that it's gone when the 3.2 release opens the project without issues.

Looks like the 3.2 release is ok and does not crash. Thanks!
