The error message is similar to issue 51648 that we have been getting intermittedly, but it happens on every build with 1.30.1 stable so we're stuck on 1.29.2

Does this happen with your code only (if yes, can you show?), does it happen with every code (e.g. fn main() {println!("Hello!");})

Can't really replace the program in this environment where the only difference between failing and successful builds is that we swap out the rust release number passed to rustup at the beginning of the build script. It's a huge project and I suspect it might happen when compiling dependencies (can you tell what module is compiled when the error happens from the logs below?)

Sometimes the error also has this "already borrowed error" (included below) as part of the stack. Could that be new for 1.30.1? (while the "specified instant was later than self" is the old intermittent failure that's been reported on multiple versions in issue 51648)
