--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. backtrace eventually lands in ranger territorry:
0x1a9808e irange::operator==(irange const&) const
/space/rguenther/src/gcc/gcc/value-range.cc:1297
0x2e65f02 range_operator::fold_range(irange&, tree_node*, irange const&, irange
const&, relation_trio) const
/space/rguenther/src/gcc/gcc/range-op.cc:271
0x2e6cf9d operator_lshift::fold_range(irange&, tree_node*, irange const&,
irange const&, relation_trio) const
/space/rguenther/src/gcc/gcc/range-op.cc:2246
0x2e77330 range_op_handler::fold_range(vrange&, tree_node*, vrange const&,
vrange const&, relation_trio) const
/space/rguenther/src/gcc/gcc/range-op.cc:4583
0x2cf743d fold_using_range::range_of_range_op(vrange&,
gimple_range_op_handler&, fur_source&)
/space/rguenther/src/gcc/gcc/gimple-range-fold.cc:589
...
possibly crossing some type boundary through relations?
