For this kind of example, tsnippet.trust-in-soft.com is always the most up-to-date (but is only sometimes broken because of being too bleeding-edge).
As for this example, no UB on a platform where int is wider than char(>99.9% of platforms) or where char is unsigned, LOL (0.1%?)

char is unsigned on PowerPC and ARM.
