Segmentation violation when using --profile mercator on tumgis/ctb-quantized-mesh

[bertt]

Hi,

I noticed the --profile mercator option gives an segmentation violation on Docker image tumgis/ctb-quantized-mesh but not on tumgis/ctb-quantized-mesh:alpine.

Sample on tumgis/ctb-quantized-mesh:

$ ctb-tile -v -f Mesh --profile mercator -C -N -e 0 -s 10 -o tiles test.tif
Segmentation fault

Any idea why this function works on tumgis/ctb-quantized-mesh:alpine but not on tumgis/ctb-quantized-mesh ?

I prefer to use tumgis/ctb-quantized-mesh instead of tumgis/ctb-quantized-mesh:alpine (because other tooling on that Docker image)

Hey there,

as shown here, the Alpine image runs on GDAL v3, the Debian image on GDAL v2. I assume that this causes the difference.

If somebody manages to get the Debian image built with GDAL v3, that would be great. I'm happy for PRs to resolve this. Sadly, I don't have time to fix this on my own.
