I tried to compile code I was working on, which by my mistake tried to call a return value of non-existing function and I got ICE.

Source:

fn main() { [].does_not_exist()(); }

Result:

panic.rs:1:16: 1:32 error: type `[_, ..0]` does not implement any method in scope named `does_not_exist`
panic.rs:1 fn main() { [].does_not_exist()(); }
                          ^~~~~~~~~~~~~~~~
error: internal compiler error: unexpected panic
note: the compiler unexpectedly panicked. this is a bug.
note: we would appreciate a bug report: http://doc.rust-lang.org/complement-bugreport.html
note: run with `RUST_BACKTRACE=1` for a backtrace

typeck: Make the supplied parameters to be a tuple
21d12c0 
When a type error occurs, check_method_argument_types() tries to provide
arguments filled with ty::mk_err(). However, if a function takes the
parameters as a tuple, the arguments should be converted to a tuple
before being passed to check_argument_types().

Fixes rust-lang#19521.
