[PROJ] Transformation failure -- valid?

[Nyall Dawson]

Hi list,

Another one from me. Attempting to reproject from WGS84 to web mercator:

PJ* crs = proj_create_crs_to_crs( 0, "+proj=longlat +datum=WGS84
+no_defs", "+proj=merc +a=6378137 +b=6378137 +lat_ts=0 +lon_0=0 +x_0=0
+y_0=0 +k=1 +units=m +nadgrids=@null +wktext +no_defs")
PK* res = proj_normalize_for_visualization( 0, crs );

Throws an error -61 when trying to reproject the coordinate -68.2 /
70.8 using res.

What am I missing?
