Comment (by teor):

 It wouldn't surprise me if we have a zstd version incompatibility here. Or
 maybe truncated input data?

 Truncated input data would definitely explain why zstd can't make any
 progress, but isn't returning an error code. In that case, it's our fault
 for not giving zstd enough data to work with. (And not failing the loop
 quietly?)

 Because if it were corrupt data, it really should return an error:
