[GitHub] [incubator-doris] BiteTheDDDDt opened a new pull request #7221: [Bug] fix core dump at some bitmap function
BiteTheDDDDt opened a new pull request #7221:
URL: https://github.com/apache/incubator-doris/pull/7221
## Proposed changes
`select bitmap_xor(bitmap_from_string('1'), bitmap_from_string('1,1'));`
`https://github.com/greg7mdp/parallel-hashmap`
```
The btree containers are direct ports from Abseil, and should behave exactly the same as the Abseil ones, modulo small differences (such as supporting std::string_view instead of absl::string_view, and being forward declarable).
When btrees are mutated, values stored within can be moved in memory. This means that pointers or iterators to values stored in btree containers can be invalidated when that btree is modified. This is a significant difference with std::map and std::set, as the std containers do offer a guarantee of pointer stability. The same is true for the 'flat' hash maps and sets.
```
