Hello Vincent,

Sorry for the delay. Your code looks correct; it seems the dictionary 
content is corrupted by some other factor and the error you see is just 
the result of corrupt dictionary.
- are you trying to modify the content of the dictionary in your code?
- otherwise, maybe try using valgrind or similar tool to find out if 
your are corrupting that memory randomly...

Sorry for not being more helpful here.

Kind regards,
Sebastien.
