When I call PJ *p = proj_create_crs_to_crs( PJ_DEFAULT_CTX, "+proj=longlat +ellps=GRS80 +no_defs", "+proj=longlat +datum=WGS84", NULL ); It returns a valid projections with the srs "+proj=noop". However, I see that it throws four exceptions in the process, all like Exception thrown at 0x752D8712 in MARPLOT Server.exe: Microsoft C++ exception: std::invalid_argument at memory location 0x0682C4B0. Unfortunately I don't have symbols tied to the built GDAL library I'm using. Can you tell me if those exceptions are expected, if they indicate something wrong, and if so how I should fix? (Obviously in this case I could note that both srs have "+proj=longlat" in the string and not create the projection at all, but I'd like to leave the code general and let it handle this case with the noop.)
