Calling parse_ini_file with invalid ini file do not take the usual error handling path

``` php
<?php

set_error_handler(function() {var_dump(func_get_args());});
@parse_ini_file(__FILE__);
```

displays "syntax error, unexpected JUNK, expecting $end or TC_SECTION or TC_LABEL or END_OF_LINE".

But the error should be @-silenced, and the user error handler should be called also.
