Hi list.

We're running a dataset via WFS (Geoserver 2.16) into QGIS.
The user has snap turned on while digitizing/editing, and too often this combo 
results in QGIS crashing.

However, this crash does not happen when digitizing/editing, but during other 
operations like panning the map or something similar.

The stack dump mentions "snapPoint", "snapToMap", "nearestVertex", and 
"closestVertex", which to me implies the snapping function in action.
It also mentions "canvasMoveEvent", which to me implies a panning operation.

I expect the snapping operation to be entirely local, i.e. independent of 
actual data source type, but this apparently only happens when using a WFS data 
source.

Can anyone shed some light on this unexpected behavior ? Is it a bug ?

Here's the crash dialog box:

QGIS is version 3.16.10, as the stack dump shows.
