Apparmor parser fails w/cx rules and CRLF line endings

The following profile should not cause the parser to fail:

$ file cx_dos_line_endings_1.sd
cx_dos_line_endings_1.sd: ASCII text, with CRLF line terminators
$ cat -n cx_dos_line_endings_1.sd
     1 #
     2 #=DESCRIPTION cx w/ dos line endings
     3 #=EXRESULT PASS
     4 #
     5 /usr/bin/foo {
     6 /bin/cat cx,
     7 /bin/foo Cx,
     8
     9 unsafe cx /bin/bar,
    10 cx /bin/a,
    11
    12 profile /bin/cat {
    13 /bin/cat mr,
    14 }
    15
    16 profile /bin/a {
    17 /bin/a mr,
    18 /tmp/slurp* rw,
    19 }
    20
    21 }
$../../../apparmor_parser -qQ cx_dos_line_endings_1.sd
AppArmor parser error for cx_dos_line_endings_1.sd in cx_dos_line_endings_1.sd at line 10: syntax error, unexpected TOK_MODE, expecting TOK_END_OF_RULE

Note that the same file with regular unix LF line endings parses okay:

$ file simple_ok_cx_1.sd
simple_ok_cx_1.sd: ASCII text
$ cat -n simple_ok_cx_1.sd
     1 #
     2 #=DESCRIPTION test cx
     3 #=EXRESULT PASS

     5 /usr/bin/foo {

     9 unsafe cx /bin/bar,
    10 cx /bin/a,
    11
    12 profile /bin/cat {
    13 /bin/cat mr,

    16 profile /bin/a {
