    Description

      Here's what I get when I run it:

              Test   Threads  Cycles
      ------------------------------
      WARNING: Logging before InitGoogleLogging() is written to STDERR
      F0412 19:52:08.029077 25130 locks.h:145] Check failed: (*__errno_location ()) == 0 (2 vs. 0) No such file or directory
      *** Check failure stack trace: ***
      Aborted (core dumped)
      

      After some digging, the problem is in base::NumCPUs, which, by the way of InitializeSystemInfo, fails to open /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq and /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq (the /cpufreq subdir doesn't exist in my VM). These failures are non-fatal, but InitializeSystemInfo doesn't reset errno before returning, and locks.h complains about that.

      I didn't see any open issues filed about this in gperftools. Not sure if we care enough to file one, or whether this is a bug in our code (locks.h).
