Exceptions thown in a function/method been called via 'call_user_func' or
'call_user_func_array', have key 'file' and 'line' disappeared in
their first element (array[0]) from Exception::getTrace().
<?php
function test() {
debug_print_backtrace();
throw new Exception('1');
}
try {
test();
} catch (Exception $e) {
var_dump($e->getTrace());
}
function callback() {
call_user_func('test');
}
try {
callback();
} catch (Exception $e) {
var_dump($e->getTrace());
}
?>

Similar result given by debug_print_backtrace(), is this a bug or an unexpected feature ? XD
