[gdal-dev] Failure to convert to Airy

[Joaquim Manuel Freire Luís]

Right. I changed the signature and removed the CPLFree() and now in GMT it also ... half works. The middle warnings are print from GMT but the other come from GDAL and are like those you suppressed in your gdaltransform commit. 

So, I should try to catch this type of cases where one can do the direct transform but not the reverse. Any place where I can search what other then Airy have the same issue?
