Parse error: syntax error, unexpected '}'

I added a piece of code to the end of my functions.php and am now getting this error –

Parse error: syntax error, unexpected ‘}’

its at line 851, which I am pretty sure is the very end (ie the bit I changed). Its currently

}

function theme_ob_get_clean() {
global $theme_ob_stack;
ob_end_flush();
return array_pop($theme_ob_stack);

Can anyone help please?

Thanks ??
