Hi Yves,
See the limitations of the split mode described at:

http://root.cern.ch/root/HowtoWriteTree.html
in section "Making a Tree with many branches"

We intend to remove this particular limitation in the split mode
using the array length information that can be now specified
in the comment field of the array declaration.
