Crash when exporting rendered raster to EPSG:3857

[HenrikJanPersson]

User Feedback

Loaded a GeoTIFF which I colorized using pseudo-colors.
Wanted to export the rendered image, but in the web projection epsg:3857, which appears to cause QGIS to crash. Exporting in for example epsg:3006 works perfect.
Have Qgis installed through osgeo4w64.

@HenrikJanPersson please attach/link a sample of a raster we can use to replicate this issue.

[HenrikJanPersson]

the file limit size was 10 mb, and when I cut only a very small part of the raster, qgis does not crash. I have therefore cut a reasonably small part of the raster, which is ~70mb, which still causes qgis to crash.
It is available here until 22 jan 2020: https://transfernow.net/70863911sy7j

@HenrikJanPersson Crash confirmed on Windows, not on Linux. QGIS 3.10.1 in both cases.
