`GetHeapRanges()` could return two overlapping ranges because it did not check whether `heap_pointer1` lies within the range returned for `heap_pointer2`. This could result in a test failure in `test_find_ranges_in_memory_two_matches` when `process.FindRangesInMemory()` returned 3 instead of 2. The patch ensures that `GetHeapRanges()` returns either two non-overlapping ranges or one range covering both heap pointers. The issue was probably introduced in #111951
