References with lifetime parameters in constant call to size_of crashses rustc

[IsaacOscar]

The following simpl file causes rustc to panic when compiling:

struct Foo<'a>
{
    a: [u8; std::mem::size_of::<&'a mut u8>()]
}

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

note: rustc 1.24.0-nightly (1956d5535 2017-12-03) running on x86_64-unknown-linux-gnu

note: run with `RUST_BACKTRACE=1` for a backtrace

Oh,
removing the lifetime parameter in the type passed to size_of does not panic:

struct Foo<'a>
{
    a: [u8; std::mem::size_of::<&mut u8>()]
}

Triage:
This is no longer ICE with the latest nightly (min_const_generics forbid the case): https://play.rust-lang.org/?version=nightly&mode=debug&edition=2018&gist=c8200436be73d107af9c0b11979d0059
