Solutions

1. Free memory or run vecsum on a host with sufficient RAM; the stopwatch struct is tiny, so this indicates severe memory pressure.
2. Check for earlier leaks in the process that consumed available memory.

When it happens

Trigger: Allocation of the stopwatch structure failed in vecsum setup.

Common situations: Extremely low available memory when launching the vecsum benchmark binary.
