Annotation fails for South Pole projection

A north pole map like so works fine and adds the desired labels every 60 deg

pscoast -Dc -W1 -R0/360/35/90 -JA0/90/6 -Ba60 >

However, if I do

pscoast -Dc -W1 -R0/360/-90/-35 -JA0/-90/6 -Ba60 >

for a south pole map, there are no annotations. What am I missing?


(6.4.0_9c89f6a_2022.03.26 from github a few minutes ago)

Hm, I am getting annotations for that example. Any gmt.conf file causing trouble?

Indeed, thanks, and sorry! (I had WeSn set somewhere to save white space on rectangular maps.)
