            Bug ID: 49019
           Summary: preprocessor inserts additional \r into commented
                    lines
           Product: clang
           Version: 11.0
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org

When running preprocessor with -E -C option (keep comments), an additional \r
is inserted at the end of every commented line inside a block comment.

Example:
/****\r\n
 *\r\n
 ****/\r\n

clang -E -C
/****\r\r\n
 *\r\r\n
 ****/\r\n
