segmentation fault (core dumped) with cuckaroo_cpu_avx2_xx plugin on ubuntu 18.04

When running with cuckaroo_cpu_avx2_xx miner plugins, grin-miner always be stop with below error

segmentation fault (core dumped)

it's no problem with miner plugins: cuckatoo_mean_cpu_avx2_31 and cuckaroo_cpu_compat_29

It crashes for me on both i7 and i9 CPU. The stack trace shows:

Thread 9 "grin-miner" received signal SIGSEGV, Segmentation fault.

Should be fixed by tromp/cuckoo@7454620

To fix this before the next grin-miner update, you can run
git submodule update --remote --recursive
and rebuild grin-miner

it seems I still have problem with cuckaroo_cpu_avx2_29 miner plugin

Note that I needed a fix in another place too. Are you using tromp/cuckoo@a074dcc or a later commit?

I will recheck later. I just run git submodule update --remote --recursive and rebuild

[tromp]

Let me know if you still have crashes...
