BUN segmentation fault 0x #8736
Description
Description
I'm getting BUN segmentation fault 0x0 very frequently on windows. it reports version of bun 1.3.6 (i've installed the bun to the latest one manually 1.3.7, but still reports 1.3.6 when OpenCode crashes). I've noticed this is happening when the AI uses the rgrep search across multiple files/folders/content. I'm experiencing this issue with the GPT5.2 if that matters.
Plugins

This issue might be a duplicate of existing issues. Please check:
All of these involve Bun segmentation faults on Windows with version inconsistencies. Feel free to ignore if your specific case (rgrep search triggering the crash) addresses a unique scenario.

Can you open an issue on bun repo? This is a bug in bun itself, not opencode

@rekram1-node Can opencode update the version of bun? It seems that the latest version 1.3.6 of bun has fixed this issue.
