[gdal-dev] Failure to convert to Airy

[Joaquim Manuel Freire Luís]

Well, I call it via GMT but that test is in GMT for a while and it used to pass.

Anyway, I'll have to investigate this further because I rebuilt GDAL and now the gdaltransform works, but when I call it from GMT is still fails.

The code is

https://github.com/GenericMappingTools/gmt/blob/master/src/gmt_ogrproj.c#L27

and a quick debug shows that the failure occurs the second time that function is called. For some reason that I don't remember right now, I have to call it twice.

(I've to go now for > 1 hour, so won't be able to reply in case of)
