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](<https://github.com/oven-sh/bun/tree/d885ce7fad3cdd28992cfd9fdbf4ec4e8c9e3c77>)) on windows x86_64_baseline [_]

Segmentation fault at address 0xFFFFFFFFFFFFFFFF

• [StringImpl.h:368](<https://github.com/oven-sh/bun/blob/d885ce7fad3cdd28992cfd9fdbf4ec4e8c9e3c77/D:/bun/build/release/cache/webkit-4a6a32c32c11ffb9/include/wtf/text/StringImpl.h#L368>): WTF::StringImpl::rawHash

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?

I don't know
