Description

The pre-compiled binaries for the CLI (e.g., kilo or the opencode native
binary) crash immediately upon execution with an Illegal instruction
(core dumped) error on older (but still common) x86-64 CPUs that support
AVX but do not support AVX2 (e.g., Intel Ivy Bridge i7-3770).

This suggests the binaries are being compiled with a high architecture
baseline (like GOAMD64=v3 or equivalent compiler flags) that requires
AVX2/BMI2.

I am the real human here, I was informed of the issue above through my agent which tried to install the open code and kilo code. they both had the same issue. hope you guys can take care of this for me please. the hardware I am using is my old desktop, that I would want to install the agent on and have it kind of sandboxed, if I am missing anything please let me know.

Plugins

none

OpenCode version

latest

Steps to reproduce

  1. Install the CLI on a machine with a CPU like the i7-3770.
  2. Run kilocode --help or opencode --help.
  3. Observe the crash: bash: line 1: [PID] Illegal instruction (core
    dumped).

Screenshot and/or share link

No response

Operating System

@miladnoo I also had this issue on an i5-3320. Today I tried again with the new v1.2.2, and that worked for me.
