Thank you Julien that was it! I moved my filters declarations as class members
and now it works.
So out of curiosity I looked at other applications using the
std::vector<itk::ProcessObject::Pointer> method. They handle upcasting between
smart pointers with:
m_Ref.push_back(filter.GetPointer());
is that ok? I mean itk::SmartPointer knows not to delete "filter" when it goes
out of scope even though it was copied via a raw pointer and not copy
constructor? pretty cool, i didn't know that!

Objet : Re: [otb-users] GDALImageIO error
Most importantly you forgot the one rule when writing applications :
images are written after DoExecute() method call ended, so any local
variable (and thus, all your filters) declared in DoExecute() does not
exist anymore when trying to write the image.
You can have a pointer to each of the filters as class member, but
something most convenient is to have a
std::vector<itk::ProcessObject::Pointer> m_Filters member and to add all
your filters to it.

Julien
