Our current base image ships 3.13.14 so it is being compiled on your system.
Can you try reproducing the error with the benchmark script from [the commit](https://github.com/ohler55/oj/commit/a455c389c0bd09cb591d1144e9366fc3f3280da0):
```plaintext
○ → docker run --rm -it -u discourse discourse/base:2.0.20220621-0049 bash
discourse@313d7af3be39:/$ cd
discourse@313d7af3be39:~$ gem install --user pry benchmark-ips oj
…
Successfully installed oj-3.13.15
5 gems installed
discourse@313d7af3be39:~$ /home/discourse/.local/share/gem/ruby/2.7.0/bin/pry
[1] pry(main)> require 'benchmark/ips'
require 'oj'
def json(string)
"\"#{string}\""
end
Benchmark.ips do |x|
x.warmup = 5
x.time = 20
json_0 = json('a' * 0)
json_64 = json('a' * 64)
json_128 = json('a' * 128)
x.report('Oj.load [0]') { Oj.load(json_0) }
x.report('Oj.load [64]') { Oj.load(json_64) }
x.report('Oj.load [128]') { Oj.load(json_128) }
end;
```
You can also check whether or not it was compiled using the problematic instruction with:
```plaintext
discourse@313d7af3be39:~$ objdump -d /home/discourse/.local/share/gem/ruby/2.7.0/gems/oj-3.13.15/lib/oj/oj.so | grep -C3 pcmpestri
2e32b: 0f 82 b5 03 00 00 jb 2e6e6
2e331: 66 0f 6f 05 77 d6 01 movdqa 0x1d677(%rip),%xmm0 # 4b9b0
2e338: 00
2e339: 66 0f 3a 61 07 00 pcmpestri $0x0,(%rdi),%xmm0
2e33f: 83 f9 10 cmp $0x10,%ecx
2e342: 74 dc je 2e320
2e344: 48 63 c9 movslq %ecx,%rcx
```
If so, this is probably something to report to the oj gem’s project.
