There's a stray space between '16' and ')' here.

This comment should not use '()' (see the GNU Coding Standards, '()'
should not be appended to a function name to indicate that it's a
function, only to indicate a function call with no arguments).

Missing space before '(' in call to __builtin_return_address.
