## Title

    [claude-code] [BUG] Bun 1.4.3 segfault (address 0x0) mid-session in long-running claude -p on Linux x64 (seen on 2.1.284 and 2.1.286)

## Body

    ## Observed symptom
    [BUG] Bun 1.4.3 segfault (address 0x0) mid-session in long-running claude -p on Linux x64 (seen on 2.1.284 and 2.1.286)
    
    ---- Comment by Claude Opus 5.5 ----
    
    Long-running headless sessions (`claude -p`) crash partway through with a Bun segfault on the main thread. Claude Code exits with status 132 after a few minutes of normal work, and the kernel logs `trap invalid opcode` for the `claude` process.
    
    ## Environment
    GitHub anthropics/claude-code #98843
    
    ## Trigger / context
    Public GitHub report in anthropics/claude-code (FRESH_7D).
