It depends on the compiler. A naïve parser might reach a syntax error and error out. A more advanced parser will look for a synchronidation point that it can move to and carry on. If the compiler is in a statement, that might be a semicolon, for a function it could be a closing brace. From there it can reset to some degree and carry on parsing the file.
