grdcontour hanging #8387

Closed macpurity closed 8 months ago

macpurity commented 8 months ago

grdcontour gets hung when fed a grid file that has values very close to zero, but not exactly zero.

Please see the post on the GMT forum page. Data and two-line script were posted there.

Can you please try if my fix fixes it too?

macpurity commented 8 months ago

Joaquim, not sure if that was directed to me, but I updated GMT to 6.6.0_09d27ad_2024.03.03 and it still hangs on my system.

John, it was actually meant to Dongdong but meanwhile I checked that this fix also fixes #6738 so I'll be merging this soon. To test it you need to build the branch, not from master.
