Illegal instruction (core dumped)

[saturn99]

i attempted to run this command in docker :

> npx wrangler dev

 ⛅️ wrangler 4.13.2
-------------------

No bindings found.
⎔ Starting local server...

✘ [ERROR] write EPIPE
.......

After many unsuccessful attempts, my attention was drawn to the workerd file;

This file gives an Illegal instruction error when executed and causes the entire Wrangler program to fail to continue working; I manually changed the program version to version v1.20250409.0, but the problem still persists.

I tested with version 2024-12-30 and it ran without problems; however, due to incompatibility with Wrangler, I am unable to test further.

What OS and CPU are you running workerd on? SIGILL is often caused by memory corruption, but if if the crash is due to actual illegal instruction it could be due to the OS and hardware requirements changing (these are documented in README.md and support relatively old x86_64 hardware still).
