ICE: defining static with struct that contains enum with &'static str variant

[arjantop]

If you change char in Test to int the error is gone, also adding another field or switching field positions in Test has the same effect.

Example:

pub enum Foo {
    Bar,
    Baz(&'static str),
}

pub static TEST: Test = Test {
    foo: Bar,
    c: 'a'
};

pub struct Test {
    foo: Foo,
    c: char,
}

fn main() {
}

Error:

{ { i8, [23 x i8] }, i32 } { { i8, [23 x i8] } { i8 0, [23 x i8] undef }, i32 97 }
{ { i8, [7 x i8], [2 x i64] }, i32 } undef
error: internal compiler error: const expr(17: Test{foo: Bar, c: 'a',}) of type Test has size 28 instead of 32
note: the compiler hit an unexpected failure path. this is a bug.
note: we would appreciate a bug report: http://static.rust-lang.org/doc/master/complement-bugreport.html
