What's Wrong?

I'm workign with Claude Code to build a reverb plugin, and as it's factoring the code, I get this same crash every session, and have to restart.

Bun v1.3.5 ([1e86ceb](<https://github.com/oven-sh/bun/tree/1e86cebd74a5723e818b5c0555276b646bcf0e4c>)) on windows x86_64_baseline [_]

Segmentation fault at address 0x1D0A823D1E4

• 7 unknown/js code

Features: spawn, standalone\_executable, process\_dlopen, Bun.stderr, Bun.stdin, Bun.stdout, WebSocket, abort\_signal, fetch, jsc

What Should Happen?

There seems to be a needed patch or update to Bun, as that's the crash that happens.
