What's Wrong?

I am using claude code to examine IDA assembly code; when it analyzes certain dissasembled code it crashes with a BUN error. The error has been reported to BUN.

The following is the BUN Call stack:

Bun v1.3.10 (d885ce7) on windows x86_64_baseline [_]

Segmentation fault at address 0xFFFFFFFFFFFFFFFF

• StringImpl.h:368: WTF::StringImpl::rawHash
• MathCommon.h:201: JSC::toUCPUStrictInt32

Features: spawn, standalone_executable, process_dlopen, Bun.stderr, Bun.stdin, Bun.stdout, fetch, jsc

What Should Happen?

well it shouldn't crash :)

oh no: Bun has crashed. This indicates a bug in Bun, not your code.

Steps to Reproduce

I cannot share the assembly it is analyzing publicly; it's copywritten code. Not sure what part of it is causing the crash but it's the result of a disasm(paddr) text result from IDA

Claude Model

Sonnet (default)

Is this a regression?
