Windows incremental compilation error: Data Area Passed to a System Call Is Too Small

Problem

Steps

1. cargo new hello
2. cargo run --

output

   Compiling hello v0.1.0 (Z:\hello)
error: incremental compilation: error canonicalizing path `Z:\hello\target\debug\incremental\hello-cevblbahc1gh`: Data Area Passed to a System Call Is Too Small。 (os error 122)

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 1.30.1 (1433507eb 2018-11-07) running on x86_64-pc-windows-msvc

note: compiler flags: -C debuginfo=2 -C incremental --crate-type bin

note: some of the compiler flags provided by cargo are hidden

error: Could not compile `hello`.

To learn more, run the command again with --verbose.

if i run with release mode ,there is no error code

cargo run --release --
that is running ok

i used virtual disk on ram file system on z:
i run in windows 7 sp1

Possible Solution(s)

Notes

Output of cargo version:

Thanks for the report! I've transferred this to the rust-lang/rust repo as this looks like a bug activated by incremental compilation. The error here looks quite scary!

error: incremental compilation: error canonicalizing path `Z:\hello\target\debug\incremental\hello-cevblbahc1gh`: Data Area Passed to a System Call Is Too Small。 (os error 122)

The implementation of canonicalize for Windows is here and comes from this location.

What I don't understand is that we should handle ERROR_INSUFFICIENT_BUFFER here (what exit code 122 is) and resize the buffer..

Curious! Do you perhaps have instructions for how to set up a ram filesystem to reproduce this? I wonder if perhaps there's a driver in play that's acting oddly?

There are already multiple existing issues open of Rust having issues with canonicalization on RAM drives.

Could this be a duplicate of #48249 ?
