[R-sig-Geo] Strange spatial reference system netCDF [stars and sf functions not working now]

[maurizio marchi]

Dear all,
Thanks for your time. Unfortunately the solution the community (i.e. 
Edzer Pebesma, https://github.com/r-spatial/stars/issues/175) is not 
working anymore. Does anyone knows why the code is now broken? Here the 
output of the old R code...
