This also includes 32-bit AMD and VIA (former Cyrix) processors, and processors like the Athlon XP and Intel P4 Xeon. However, Debian GNU/Linux buster will not run on 586 (Pentium) or earlier processors. """ I let you check if that's all right for your host cpu. So if i run qemu with the first P6 cpu that comes to mind, pentiumpro, npm install electron-spellchecker@1.1.2 no longer crashes. That doesn't prove there is no crash on a supported cpu, but that's a start. Comparing the flags and address sizes might help. Also upstream nodejs does not support 32bit cpu on linux platform.
