Ok, I don't have any idea by just looking at the backtrace.

Nathalie, was there any reason for calling the unregister hook so late?
It should rather go as soon as the beginning actually, so that the hook
operations are properly waited for by the rest of
_starpu_data_unregister.  I don't think it is the bug at stake, however.

Benoît, would you have a simple example that triggers the bug?
