Hi Guillaume,

We could try upgrading ossim to 2.8.2. maybe that contains a fix.

Since you're building OTB yourself, it's unlikely to be an ABI break
issue due to the otb package being built with an old version of ossim.

I didn't want to touch ossim in anticipation of the OTB 7 which won't
require it any more, but I guess I don't have much of a choice.

Please try to reproduce the issue when ossim (2.8.2-1) is available
unstable.

Kind Regards,

Bas
