See section 5.9 of the Bison info file:

    By defining the macro `YYMAXDEPTH', you can control how deep the
    parser stack can become before a stack overflow occurs.  Define
    the macro with a value that is an integer.  This value is the
    maximum number of tokens that can be shifted (and not reduced)
    before overflow.  It must be a constant expression whose value is
    known at compile time.
    [...]
    The default value of `YYMAXDEPTH', if you do not define it, is
    10000.
