Invalid or corrupt file when "releasing" on MSVC

[jerryc05]

For a tiny program like this:

fn main() {
  println!("{:?}", instant::Duration::from_secs(1));
}

when running in debug mode, nothing bad happens, but when I run in release mode, I got this error:

  = note: LINK : warning LNK4044: unrecognized option '/s'; ignored
          [hidden]\tiny-ffmpeg-gui\target\release\deps\instant-bce189fdb2307e6a.instant.dt1bllbr-cgu.0.rcgu.o : fatal error LNK1107: invalid or corrupt file: cannot read at 0x55C


error: aborting due to previous error

error: could not compile `instant`.

Which rustc version are you using? is LTO enabled?

I think it is an issue introduced as of nightly-2020-05-08 and related to LTO. However, it just appears in some crates like this one.

Can confirm, rolling back to 2020-05-07 fixes the problem.
