Heatmap renderer caused QGIS to Crash

[Skudger]

I created a heatmap view of about 3k data points. Zooming or panning consistently cause QGISI to crash. rash ID: dc10474b86d3cbb790ade7fb82aad1f4facfb54f

@Skudger please attach/link the data and the detailed parameters for the heatmap. Also try with a new QGIS profile.

Giovanni,

Thanks for looking into this.

I tried a new profile. It did not affect the crashing behavior.

The data is proprietary, but I have included the record layout and the first 10 records. It is similar to data I have used in the past without issues.

I am not sure what you mean by the detailed parameters for the heat map...Symbology?

Thanks,

Michael

so give us an idea: CRS? type of datasource? geographic extension?

yes, the exact options/configs you used to generate the heatmap.

Giovanni,

Below are screenshots of the symbology tab in the layer properties.

Thanks,

@Skudger no image attached as also missing the other infos I asked.

I believe I found the issue. Incompatibility CRSs. See the message below. Be helpful if QGIS could trap errors such as this and not crash.

@nyalldawson another consequence of the upgrade to proj6? is this related/duplicate of other tickets with similar reports?

[nyalldawson]

I can't reproduce...

Closing for lack of feedback. Should be anyway solved in the latest builds.
