--- Comment #5 from Iain Sandoe <iains at gcc dot gnu.org> ---
It looks likely.

is there a 32b arm box on the cfarm?
I don't have access to one locally either (but maybe it will reproduce on a
cross...)

Both places in the crash logs are=20

dummy =3D dummy ? TREE_OPERAND (CALL_EXPR_FN (dummy), 0)
                            : NULL_TREE;

where dummy is the return tree from a DTOR build, I guess that arm can retu=
rn
something other than NULL_TREE for a failed build_special_member_call()?

will try to take a look this evening.=
