ICE: `CValue::const_val for non bool/char/float/integer/pointer type Binder(extern "CCmseNonSecureCall" fn(i32, i32, i32, i32) -> i32, []) is not allowed`

auto-reduced (treereduce-rust):

fn main() {

        unsafe { core::mem::transmute::<usize, fn(i32, i32, i32, i32) -> i32>(0x10000004) };
    let mut toto = 5;
    toto += non_secure_function(toto, 2, 3, 5);
}
