Spurious CR by any chance? Only one error per line here.
Weird though, it should handle it.

Anyhow the reason it works is simple enough: the parser
is called 'initial' and here is the rule in question:
|    _        {E.parse_error
      "Invalid symbol"
     (Lexing.lexeme_start lexbuf)
    (Lexing.lexeme_end lexbuf);
   initial lexbuf}


so you can see it emits a diagnostic .. and then continues
by recursively calling itself again .. ignoring the error.
