      Description

      Random internal compiler errors are being observed when building c++ code. Initially, it was beloved this was only occurring under py2 but it has also be observed with py3.

      :::::  [2017-09-19T10:49:24.541101Z] c++: internal compiler error: Killed (program cc1plus)

      The error above was observed on el7-4, which does have OOM invocations in the system journal from early this morning. Strangely, the system was listing a surprising low amount of available memory, even after forcing a cache dump. Running processes could only account for less than 1GiB of memory in usage.

      $ cat /proc/meminfo 
      MemTotal:       14973596 kB
      MemFree:         7954100 kB
      MemAvailable:    7898996 kB
      Buffers:               0 kB
      ...
      

      A reboot seemed to add ~6GiB of available memory. It appears that there might be a slow kernel memory leak.

      $ cat /proc/meminfo 
      MemTotal:       15234532 kB
      MemFree:        14383516 kB
