just do it like this - the result will be the same, and $bar is still passed
by reference:
$result = call_user_func("foo", $bar);

function foo( &$bar ) {
    $bar .= 'foobar';
    return 1;

This error just tells you, that you have to declare "pass-by-reference" in
your functions, and cannot use a "generic" function, that sometimes takes
parameters by reference and sometimes by value. This problem has nothing to
do with "call_user_func()".
