[PROJ] Migrating to PROJ-9

[Even Rouault]

Weird indeed:

and what about trying directly the pipeline with cct :

echo 652760.73700000 7033791.24300000 43.64200000 | cct +proj=pipeline 
+step +inv +proj=lcc +lat_0=46.5 +lon_0=3 +lat_1=44 +lat_2=49 
+x_0=700000 +y_0=6600000 +ellps=GRS80 +step +proj=cart +ellps=GRS80

you should get:

  4070327.2514    166078.9321  4891298.6149           inf
