Note that it is a multi-threaded and requires 5 or more threads to fail. Number of launched threads is controlled by OMP_NUM_THREADS evironment variable, defaulting to number of hardware threads. Changing constants in the test case makes it fail with different numbers of threads. I will attach statically linked riscv64 binary executable if size limits permit.
