    [wasm][fuzzer] Handle Interpreter step limit exhaustion. · d1f566c6
    Andreas Haas authored
    If the fuzzer input cannot be executed in the interpreter within a step
    limit, then the interpreter does not calculate the result but instead
    finishes with a RangeError. The problem with the input of the bug report
    was that the interpreter finished with that RangeError, but the
    execution of the compiled code still returned a result, which was
    naturally not a RangeError and therefore caused the result check to fail.
    With this CL the compiled code is not even executed when there is a
    RangeError after the execution in the interpreter. Thereby we also
    avoid executing an infinite loop.
