Steps to reproduce:

Actual results:
The read from _BufferB happens unconditionally, leading to undefined behaviour.

Expected results:
The read from _BufferB should happen only if the condition (_BufferA[tid] < _BufferBLength) is satisfied.

Reproducible with versions:
6000.5.0a1, 6000.4.0a1, 6000.3.0a1, 6000.2.0a1, 2022.3.0a1
