I have started Windows in safe mode.
I have permanently deleted the OSGeo4W, AppData\Local\QGIS and Roaming\QGIS folders. (I don't have a previous stand-alone install in this machine.)
I have repaired the registry keys.
I have installed QGIS again.
I have rebooted the system in each step.

And it continues to fail.

Any idea where the inconvenience may be?
I'm missing a step to clean up the environment?
(I can not format drive C.)

add the exact steps you follow, or even better attach a screencast.

Screencast attached.

#5 Updated by Richard Duivenvoorde almost 6 years ago

Confirmed here with current QGIS master (on Linux):

project epsg:4326
create a new point layer and save as geopackage
add 2 points
go to edit vertex
change x coordinate to 0
crash

Could it be related to: #21325 ?

#7 Updated by Martin Dobias almost 6 years ago

I cannot replicate.

Richard, can you post your traceback from linux?

#8 Updated by Martin Dobias almost 6 years ago

Also, does it need to be a geopackage? would it crash with a temporary scratch layer too? What if you first save the newly added points - would it crash anyway?

In my case, it does not need to be a geopackage. It can be a temporary layer. Also a shapefile.

It does not need to be a points layer, can be linestrings or polygons.

Also, does not need to be when changing the coordinate to zero. Can be any integer or decimal number.

And it does not need to be in EPSG:4326. Can be any CRS.

Saving the edits don't avoid the crash.

But does not always crash on the first edit. My best record was to make three consecutive edits-saves without a crash.

#11 Updated by Gabriel De Luca almost 6 years ago

I can't reproduce it now after install qgis-dev-3.5.0-100.

It was fixed?

#12 Updated by Giovanni Manghi almost 6 years ago

Resolution set to fixed/implemented
