Per Google C++ style guide ([1]), which Chromium follows with a few exceptions
([2]), 

"""Objects with static storage duration, including global variables, static
variables, static class member variables, and function static variables, must be
Plain Old Data (POD): only ints, chars, floats, or pointers, or arrays/structs
of POD."""

Please, define a main function for this fuzzer and put this initialization into
main.
