still os error 122 on the memory file system z:\ when compiling with cargo

[jeppeter]

i found a bug on the cargo .the code in windows 7 x64 platform with rust-1.37.0-msvc

main.rs
########main.rs fle start
use regex::Regex;

fn main() {
let re = Regex::new(r"(?x)
(?P\d{4})

(?P\d{2})

(?P\d{2})
").unwrap();
let caps = re.captures("2010-03-14").unwrap();

assert_eq!("2010", &caps["year"]);
assert_eq!("03", &caps["month"]);
assert_eq!("14", &caps["day"]);

}
########main.rs file end

Cargo.toml
########Cargo.toml file start

[package]
name = "regtest"
version = "0.1.0"
authors = ["jeppeter"]
edition = "2018"

[dependencies]
regex = "1"
########Cargo.toml file end

when i set environment CARGO_INCREMENTAL=0
and i use command line

cargo build --release --verbose

i got the output

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

i have mention the bug on #65325
and it will solved in the simple hello world program ,
but ,i found it not solved in the some complicated situation

i make sure the memory file system disk is 8G size ,so it has enough disk size to contain the temporary file
i make also sure that the code can be compile ok on the normal disk system, i compile it ok.

Please use code fences so the issue is easier to read.

Based on the error message, this does not look like a duplicate of #52377.

The compiler doesn't work very well on ramdisks and network shares on Windows, so to work around this bug you can develop on your local file system instead.

[jonas-schievink]

Ah, nevermind, it is a duplicate of #52377. Please don't open duplicate intentionally, there's no value in having multiple issues for the same bug.
