SIGSEGV when std::time::Instant::now() called

[sunny0531]

I tried this code:

fn main() {
    let now=std::time::Instant::now();
    println!("{:#?}",now);
}

Then it crashed with signal SIGSEGV
signal SIGSEGV: address not mapped to object (fault address: 0x680)

Do you have a stack trace?

I have no problems with my nixos-unstable. Have you built this executable before doing an update and it segfaults now after the update? That happens sometimes with nix and isn't a bug in rust

Please retry with RUST_BACKTRACE=1? Or maybe try using gdb on the core dump...
