Root cause analysis

• Crash is Bun runtime segfault (0x13CB0 = null pointer deref), not OpenCode logic
• 174s hang before crash = "stuck at reading file"
• Peak RSS 0.66GB — memory pressure from file read code paths (v1.17.0 fff-backed search) triggers Bun bug
• Upstream issue #32237: file reads retain search state causing memory growth

Request

• Rebuild with newer Bun runtime or repackage OpenCode v1.17.4+
• Or patch to avoid code path triggering null deref
