No, I'm not aware of such issue. Autotest suite passes fine on our tested Travis-CI + AppVeyor 
configurations.

Perhaps you can just test
gdal_translate autotest/gcore/data/byte.tif byte.gpkg -of GPKG
and see if that crashes too. And if that doesn't, then
gdalinfo -checksum byte.gpkg
And if that still doesn't cras, then investigate in the context of the actual autotest steps.

If there's just one raster tileset, this will the regular dataset. If there are several, they will be 
listed as subdatasets


$ gdal_translate autotest/gcore/data/byte.tif test.gpkg -of GPKG -co

$ gdal_translate autotest/gcore/data/byte.tif test.gpkg -of GPKG -co

0...10...20...30...40...50...60...70...80...90...100 - done.
