--- Comment #2 from Eric Gallager <egallager at gcc dot gnu.org> ---
Confirmed, although for me it also prints an additional error about my target
lacking support for decimal floating point:

$ /usr/local/bin/gcc -Wall -c 43673.c
43673.c: In function ‘main’:
43673.c:7:2: error: decimal floating point not supported for this target
  _Decimal64 e = 0.1dd;
  ^~~~~~~~~~
43673.c:9:13: warning: use of ‘D’ length modifier with ‘a’ type character has
either no effect or undefined behavior [-Wformat=]
  printf ("%Da\n", e);
             ^
