Hello everyone I’m at the “Decode bencoded dictionaries #mn6” step of the “Build your own torrent” in C.  
When I run the same test as the tester on my machine I get the expected result but the tester does not.  
Any idea please ?  
Thanks

Could you be returning an exit code other than 0? Exit code 0 indicates program executed successfully without any errors. Your output seems to match, but not the exit code. This can also happen if your application crashes or throws an error while it’s executing the code.

I think my program crash on the tester machine but not on mine. I only return 0 or 1 but never -1 so I don’t know.
