It's better if you can provide a docker image. |

By the way, you are on X86? |

Here's my system information |

Thank you, I will work on this now. |

I also reproduced this on the latest CPython 3.14 commit: python/cpython@4c14f03 |

yeah, I can reproduce, I am now working on it. |

👍 sweet. Just letting you know in case it helps narrow things down. I also produced the segfault on

The error is related to Dwarf. I am not sure what causes this, I guess dwarf type mismatch. I will try to fix it. |

Similar to #121213 but with a different trace
This assertion crashes BOLT during a CPython build. I'm using the 3.13.1 tag for reproducibility.
My usage looks like
I'll try to create a reproduction in a Dockerfile, if that'd be helpful.
I'm using LLVM 19.1.6 on an x86_64 Arch Linux host
Here's the stacktrace
