Benchmark failed

[redseabay]

I add log line before b.fai
b.Logf("%s: error when i==%d", funcName, i)

and i noticed most i is 742, some is 178

if i change benchmarkItemCount to 512 (1<<9), i change to 385 390 403... seems it is not very random

CPU: amd ryzen 2600, ram 16G, os windows 7 64bit

BTW: race detect has no problem

my first log with an error log line:

benchmark_test.go:88: BenchmarkReadHashMapUint: error when i:742 j: %!d(<nil>)
