--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed.

914       /* Also mark the artificial SSA_NAME that points to the partition of
X.  */
915       if (TREE_CODE (x) == VAR_DECL
916           && !DECL_EXTERNAL (x)
917           && !TREE_STATIC (x)
918           && cfun->gimple_df != NULL
919           && cfun->gimple_df->decls_to_pointers != NULL)
920         {
(gdb) p cfun
$1 = (function *) 0x0

I suppose this could be made more robust by checking for cfun being non-NULL
or checking currently_expanding_to_rtl.
