Desktop 1.18.30: utility NodeService crashes intermittently on quit (SIGABRT/SIGSEGV)

[Oveth-Git]

Description

Environment:

• OpenCode Desktop 1.18.30 (deb, updated from 1.18.25), channel latest
• App running inside Ubuntu 24.04 distrobox container on Fedora Kinoite 44 host
• Native modules in crashing process: @lydell/node-pty-linux-x64 1.2.0-beta.12,
  @parcel/watcher-linux-x64-glibc 2.5.1 (verified under
  /opt/OpenCode/resources/app.asar.unpacked/node_modules/)

Repro:

1. Open OpenCode Desktop, use normally, then quit.
2. Repeat open/quit ~4 times. About 1 in 4 quits shows a crash notification
   for the utility process. 3 of 4 quits are clean.

Crash data (systemd-coredump):

• ai.opencode.desktop --type=utility --utility-sub-type=node.mojom.NodeService
  Signal 6 (ABRT) and Signal 11 (SEGV) on different quits, always at quit time.
• Core sizes 36-49 MB truncated (host limits: ProcessSizeMax=1G); one 46 KB.
• utility.log at crash second: [warn] (utility) sidecar exited { code: 0 }
• main.log clean, updater reports 1.18.30 up-to-date.
• GDB on host cannot resolve container paths (/opt/OpenCode only exists in
  container), core truncated so no symbol stack; file-backed mapping notes
  confirm pty.node + watcher.node loaded in the crashing process.

Ruled out:

• Crash reproduces with ALL MCPs disabled (enabled: false for every entry
  in opencode.jsonc), so it is not caused by any MCP server.
• Reproduced on 1.18.25 and 1.18.30.

Possibly related:

• SIGABRT crash during Electron process exit (ThreadSafeFunction cleanup race) microsoft/node-pty#904 (SIGABRT during Electron exit, ThreadSafeFunction
  cleanup race with node-pty)
• opencode#17068 (sidecar not terminated on Desktop close)

~/.config/ai.opencode.desktop/Crashpad/pending/ + utility.log snippet above.

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

• [Desktop][Linux] NodeService utility process SIGABRTs during native teardown on every close #48020: Same symptom — node.mojom.NodeService utility process terminates with SIGABRT during native teardown at quit time on Linux Desktop, with sidecar exited { code: 0 } logged at the same second. The environments differ (SteamOS/Flatpak vs Ubuntu 24.04 distrobox), but the crash signature, affected native modules (node-pty, @parcel/watcher), and timing are essentially identical.

If your issue is the same root cause, consider adding a comment there with your crash data (the Crashpad .dmp you attached here) rather than tracking it separately.

Likely same root cause as #48020 (thanks for the pointer) — same signature:
NodeService SIGABRT at quit in the same second as sidecar exited { code: 0 },
truncated dumps, historical SIGILL closes, CPU/fan load after close.

Differential data points from my side (keeping this open for the maintainer
to deduplicate):

• Intermittent here (~1 in 4 quits), deterministic there.
• Also Signal 11 (SEGV), not only Signal 6.
• Native modules loaded in crashing process: @lydell/node-pty-linux-x64
  1.2.0-beta.12 + @parcel/watcher-linux-x64-glibc 2.5.1.
• Reproduces with ALL MCPs disabled, so not MCP-related.
• Different environment: Ubuntu 24.04 distrobox container on Fedora
  Kinoite 44 host (.deb), versions 1.18.25 and 1.18.30.

Happy for this to be closed as duplicate of #48020 if the maintainer prefers.
