--- Comment #2 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Failing assertion here:
#1 0x00000000014df116 in ana::byte_range::exceeds_p (this=0x7fffffffbf80,
other=..., out_overhanging_byte_range=0x7fffffffbfc0)
at ../../src/gcc/analyzer/store.cc:464
464 gcc_assert (size > 0);
(gdb) list
459 {
460 /* THIS definitely exceeds OTHER. */
461 byte_offset_t start = MAX (get_start_byte_offset (),
462 other.get_next_byte_offset ());
463 byte_offset_t size = get_next_byte_offset () - start;
464 gcc_assert (size > 0);
465 out_overhanging_byte_range->m_start_byte_offset = start;
466 out_overhanging_byte_range->m_size_in_bytes = size;
467 return true;
468 }
where "this" and "other" are both empty, having 0 size:
(gdb) call this->dump()
bytes 1-0
(gdb) call other.dump()
bytes 0--1
due to the cst_capacity_tree in the region_model::check_region_bounds caller is
zero.
