Do not free the PROJ4 pointers at levels > 1.

[joa-quim]

With nested calls, as for example pscoast -E, if projections are done with PROJ4 we need those pointers alive when plotting the grid lines that happens only at the end.

Don't know how to test this.

[joa-quim]

Good point. The need for the change arises when this:

gmt coast -ECA+p0.2 -R-122.913612/36.214964/-9.977657/62.430681+r -J+proj=lcc+lat_0=0+lon_0=-95+lat_1=49+lat_2=77+width=15c/0 -Bpa10g10 -png lixo

Would not plot the grid lines and print lots of error messages issued from GDAL

[anbj]

I get

$ gmt coast -ECA+p0.2 -R-122.913612/36.214964/-9.977657/62.430681+r -J+proj=lcc+lat_0=0+lon_0=-95+lat_1=49+lat_2=77+width=15c/0 -Bpa10g10 -png lixo
ERROR 1: Point outside of projection domain
ERROR 1: Point outside of projection domain

But plot is made and looks good.

[joa-quim]

But you get that with the no-free-proj4-at-higher-levels branch, not master, right?

[anbj]

Yes, sorry. I get this with no-free-proj4-at-higher-levels.

[joa-quim]

So that means the fix worked for this case (I have no other to test). Enviado a partir do Outlook para iOS<https://aka.ms/o0ukef>
