Description
The script below is modified from example 46 (http://gmt.soest.hawaii.edu/doc/latest/gallery/ex46.html).
In fact, I only changed the date from 2016-02-09T16:00:00 to 2016-02-23T03:00:00:
ps=example_46.ps gmt pscoast -Rd -JKs0/10i -Dl -A5000 -W0.5p -N1/0.5p,gray -S175/210/255 -Bafg --MAP_FRAME_TYPE=plain -K -Xc > $ps gmt pssolar -R -J -Td+d2016-02-23T03:00:00 -Gnavy@95 -K -O >> $ps gmt pssolar -R -J -Tc+d2016-02-23T03:00:00 -Gnavy@85 -K -O >> $ps gmt pssolar -R -J -Tn+d2016-02-23T03:00:00 -Gnavy@80 -K -O >> $ps gmt pssolar -R -J -Ta+d2016-02-23T03:00:00 -Gnavy@80 -K -O >> $ps gmt pssolar -I+d2016-02-23T03:00:00 -C | gmt psxy -R -J -Sksunglasses/1.5c -Gyellow -O >> $ps
Then pssolar exits with segmentation fault.

Yep, for the current example and for -Tn or -Ta, in gmt_plot.c#L5640
/* 1. Calculate the path from yc to pole: */
perim_n = gmtlib_lonpath (GMT, start_lon, pole_lat, yc, &x_perim, &y_perim);perim_n = 0 and troubles follow. In this case pole_lat yc 90, so maybe just needs a test to catch these type of cases.

So is x_perim and y_perim NULL then? I could add a check to avoid the memcpy of those vectors.

They look but not exactly sure what allocating zero elements does to a pointer.

I think this is now fixed in r17298. Dongdong's example works for me.
