    [wasm] Allow for arbitrarily long error messages · 072d0e3e
    Clemens Hammacher authored
    We currently have a fixed limit of 256 characters for error messages
    generated in the decoder. However, we sometimes embed names in it,
    which makes it easy to generate a crash by using long names (e.g. for
    exports) in invalid wasm modules.
    This CL fixes this by switching to a stream based interface, allowing
    to pass arbitrary objects to be printed. With this interface, we can
    easily limit the length of output later.
