Segmentation fault on v0.7

[evetion]

In upgrading GeoDataFrames to ArchGDAL 0.7 (evetion/GeoDataFrames.jl#21) I hit a segmentation fault. I can reproduce it to the following code on macOS when using Julia 1.6. 1.7 seems to work, but most of the platforms fail the CI in the PR.

using ArchGDAL; const AG=ArchGDAL

AG.createlayer(
    name="test",
    geom=AG.GDAL.wkbPoint,
    ) do layer
        AG.addfielddefn!(layer, "test", convert(AG.OGRFieldType, String))
end

results in

I'm not able to reproduce the error in #212 (comment), but it resulted in an error for me nonetheless:

Am now able to reproduce when I replace AG.GDAL.wkbPoint with AG.wkbPoint in #212 (comment).
