If the file ends with a CXX comment (`// …`) and is not followed by a trailing newline / linefeed, `unifdef` fails with an error: ```console $ printf '// bar\n' | ./unifdef // bar $ printf '// bar' | ./unifdef unifdef: [stdin]: 2: EOF in comment // barunifdef: Output may be truncated ``` Detect this case and just close the comment in that case.
