This seems to be a weird bug in `st_read`. If you read it with an SQL
query that matches every row it works:
> js = st_read("./countrymasks.geojson", query="select * from countrymasks
> where 1 = 1")
Reading query `select * from countrymasks where 1 = 1' from data
source `/home/rowlings/Downloads/countrymasks.geojson' using driver
`GeoJSON'
Simple feature collection with 214 features and 15 fields
Geometry type: MULTIPOLYGON
Dimension: XY
Bounding box: xmin: -180 ymin: -55.79439 xmax: 180 ymax: 83.62742
Geodetic CRS: WGS 84
But leave out the query and you get that C code level error. Another
equivalent query would be "select * from countrymasks" (without the
"where" clause) but this
triggers the error too. Very odd. Worth reporting as a bug?
