Description
Describe the bug
I crashed when building a BKT index using 1000W, 10 dimension data, and the core file shows a crash in the following code.
I tried to move the part of the shuffling algorithm out of the concurrent part, and the core phenomenon disappeared.
Desktop (please complete the following information):
- OS: Linux Ubuntu 22.04.3 LTS
- gcc Version: 11.4.0

Research direction
Start by reproducing the BKT index build with the 1000W, 10-dimension dataset on Ubuntu 22.04.3 with GCC 11.4.0, then inspect the core dump and the concurrent shuffling code shown in the issue. Done means the build no longer crashes under this configuration, with regression coverage for the reported case.
