grdselect -Ai unable to report intersection when one grid is global?

[mwoot]

Description

grdselect -Ai returns an unexpected error when trying to find the intersection between a global grid and another grid. Issue comes from my forum post.

Full script that generated the error

gmt grdcut @earth_geoid_01d_p -Rg -Gglobal.grd
gmt grdcut global.grd -R0/1/0/1 -Gsubset.grd
gmt grdselect -Ai global.grd subset.grd

Full error message

grdselect [WARNING]: No common area for all grids is possible.

Expected outcome

-R0/1/0/1

Running the intersection between two non-global grids works as expected:

gmt grdcut global.grd -R0/15/0/15 -Gbigger_subset.grd
gmt grdselect -Ai subset.grd bigger_subset.grd

System information

• Operating system: Ubuntu 22.04.5 LTS
• GMT version (gmt --version): 6.6.0

I tried a few other variations with the subset grd. When I used -R1/2/0/1 and placed the subset before the global grd eg.
gmt grdselect -Ai subset1_2_0_1.grd global.grd
then i got the subset region as the intersection. However if I put global.grd ahead of subset...grd then there is 'No common area'
After trying a few other variations it seems that if the first grid has an xmin=0, then the no common area warning results.
