Since LLVM 12 (rust-lang/rust#84230) ExceptionStackFrame has to be taken by value. See rust-lang/rust#40180 (comment).

Current output of ud2:

[0][ERROR] Invalid Opcode (#UD) Exception: ExceptionStackFrame {
    instruction_pointer: 0xc35b30c483480b0f,
    code_segment: 0xee9d058af2894850,
    cpu_flags: 0x3d8d48f76348ffff,
    stack_pointer: 0x7e8ffffffcc,
    stack_segment: 0xccccccccccc35900,
}

Expected:

[0][ERROR] Invalid Opcode (#UD) Exception: ExceptionStackFrame {
    instruction_pointer: 0x501738,
    code_segment: 0x8,
    cpu_flags: 0x11206,
    stack_pointer: 0x373be30,
    stack_segment: 0x10,
}
