Hi Mathieu,
Thanks for sending one of your files. The file is truncated to 4096 bytes
and it should be 3.2 MBytes. The recovery mechanism crashes due to a very
peculiar situation where your sub-directories fit below the 4096 bytes
and the first key of the first sub-directory starting at 4096.
I will introduce more protections such that the TFile constructor will not
crash in case of corrupted/truncated files.
