--- Comment #5 from Keith Thompson <Keith.S.Thompson at gmail dot com> ---
Mikhail: Newlines in file names (either the actual file name or via a
#line directive) cause problems with __FILE__, though that particular
problem occurs only if there's an explicit reference to __FILE__.

See Bugzilla ticket #66317.
