When executing ./pant compile <project>, I'm getting the following error stack:
(Note: "Nom de fichier trop long" translates into "Filename too long")

Also, note that when I'm trying to create the file with linux, it works without issue on the filename length:

Thank you for your help!

Drawing attention to:

...
/home/abours/.Private     ecryptfs   198G     57G  131G  31% /home/abours

So this case does involve an encrypted directory as opposed to partition which should trigger NAME_MAX being lower than expected due to ecryptfs internals using up ~100 bytes of that limit in overhead. This does not jive with the manual touch example in the problem description however.
