The minimal "physical id" in /proc/cpuinfo on my machine is 1. It isn't 0.
In function CreateThreadPool():
(gdb) p nodes[0].cores
$2 = std::vector of length 0, capacity 0
Adding "numaId--" to function CalculateProcessorTopology() fixes the
segmentation fault.
$ zgrep NUMA /proc/config.gz
# CONFIG_NUMA is not set</pre>
