No.  As stated in the revised specification:

  If the error is in a command-line argument (e.g., when
  stat() or lstat() fails on the argument to -newer, but
  not when a FILENAME does not exist), it exits
  immediately; otherwise it continues execution (e.g.,
  when opendir() fails it moves to the next file).
