--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

Looks like the code which crashes:
      PACK_EXPANSION_LOCAL_P (result) = PACK_EXPANSION_LOCAL_P (t);
      PACK_EXPANSION_SIZEOF_P (result) = PACK_EXPANSION_SIZEOF_P (t);

was added with  r12-701-ge7a9f085ffd34b0d7bc4b803c182b41 .

Note GCC 12+/11.2.0 will crash too if checking is enabled.
