--- Comment #6 from Eric Fiselier <eric at efcs.ca> ---
This has already been fixed in 4.0. I thought the fix made it into 3.9 but it
appears it didn't. The UB fixes for __tree made it in, but not the ones for
__hash_table.

Thanks for the report. Feel free to file any other UBSan bugs you find in
libc++ trunk.
