Latest opencode update on latest Bun is unusable.

[nmzpy]

Description

It crashes instantly with segfault after you try to launch let's say even 3 agents. Windows 11 latest, Git bash latest, opencode 1.2.10, bun 1.3.9

lezz get it

Used to be 100% stable a week ago by the way. Maybe this helps, do you know any hot-fixes?

WSL better?

Plugins

DCP, antigravity auth

OpenCode version

1.2.10 (not an opencode issue from what I know, we might need to give the windows people a run-back to a lower bun version)

Steps to reproduce

1. launch opencode
2. tell your agent to spawn 10 explore subagents
3. enjoy

Screenshot and/or share link

No response

Operating System

Windows 11 latest

Terminal

Windows Terminal / Wezterm too - both crash - not term issue

This issue might be a duplicate of existing issues. Please check:

• Windows segfault: Bun 1.3.9 crash during active multi-tool session (no graceful shutdown) #14204: Windows segfault with Bun 1.3.9 during multi-tool/multi-agent session (no graceful shutdown) — same OS, same Bun version, same symptom
• Segmentation fault in Bun__addrinfo_freeRequest on Windows (v1.3.9) #14096: Segmentation fault in Bun on Windows v1.3.9 — same Bun version and platform crash

If your issue is the same as one of these, please consider adding a thumbs-up or additional context there rather than opening a new report.

bun 1.3.10 supposedly fixes all these segfaults.

this is scheduled to release tomorrow.

we will upgrade asap once they release.

ensure you open that bun.report link so that the bun team can appropriately track the segfault

[Hona]

for now as a workaround - you may want to manually use the baseline opencode build for windows not the modern one

[zentala]

same here

[ndeblauw]

same here (since today) - when/how is a fix possible? I tried to remove and reinstall opencode (via npm) but that does not solve things

[horarodriguezz]

I downgraded to 1.2.10 and it works. The problem happens to me in newer versions >=1.2.11

[ndeblauw]

@horarodriguezz thanks for this tip, this was enough to get me going again :-)

[Hona]

please upgrade to latest OpenCode v1.2.15 - and try again.

There should be no more segfaults/crashes.

Can you confirm it works fine after the version is >v1.2.15 :)

Hell yea it does! Thank you
