Sorry, it doesn't work on trunk, it works on my patched trunk :p
Fixing bug #52940 would fix this. However, the patch for that bug has
one effect that changes the current behavior of call_user_func_array
(removes check for internal function) and another change when the
refcount of the zval is <= 1 and it's a reference (a rare case).
Attached a patch that changes as little as possible, yet fixes this bug.

Reproducible on PHP 5.3, but not on trunk.

Thanks for your comment: your workaround works.
However, having to redefine standard php functions like trim() or
count() just to be able to use them with array_filter() is not very
convenient, is it?
The fact is that the function behaviour changed in a "revision release"
which should not have broken my code...
;-)

Use a reference in your callback function:
function my_trim(& $a)
{
return trim($a);
}
