    [wasm] During instantiation, pending_exceptions dominate new exceptions · 5f105141
    Andreas Haas authored
    For async instantiation of WebAssembly code we had the assumption that
    a pending exceptions (an exception which comes from
    execution JS code) and an ErrorThrower error cannot occur at the same
    time. This assumption turned out to be wrong. With this CL we handle
    this case by prefering pending_exceptions over ErrorThrower errors.
    
    In addition I extended the tests for failing instantiation to also
    exercise async instantiation, and I added a regression test.
