    [wasm][debug] Handle OSR edge case · d5e0d1f7
    Thibaud Michaud authored
    When the top frame is paused at a breakpoint, and this breakpoint is
    being removed or was already removed, introduce a "dead breakpoint" in
    the new code. This ensures that:
    - The source position for the new frame is correct, otherwise it would
    just pick the source position of the previous call,
    - The offset between the source position and return address is the same
    in the new and old code, which is necessary for OSR to find the correct
    return address.
