bazel fails to build target on Windows 11 RAM disk mount with blaze_util::MakeCanonical(...) failed: (error: 1): Incorrect function.

Description of the bug:

Namaste,

While attempting to build using bazel by pointing buildkite toward a RAM mounted file system
I see the following error. I'm not sure under what conditions blaze_util::MakeCanonical fails on Windows.

[FATAL 12:14:05.257 src/main/cpp/blaze.cc:1302] blaze_util::MakeCanonical('r:\buildkite-agent\builds\windows-amd64-mustang-1\yesudeep\rules-clojure') failed: (error: 1): Incorrect function.

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

1. Create a RAM disk using ImDisk
2. Point your CI agent to use the Ram disk.
3. Have it run bazel there.

Which operating system are you running Bazel on?

Windows 11 Pro

What is the output of bazel info release?

release 6.0.0

If bazel info release returns development version or (@non-git), tell us how you built Bazel.

No response

What's the output of git remote get-url origin; git rev-parse master; git rev-parse HEAD ?

No response

Have you found anything relevant by searching the web?

• Source location:

  bazel/src/main/cpp/blaze.cc

  Line 1301 in ccfeeff

  if (result.empty()) {

• Impl:

  bazel/src/main/cpp/util/file_windows.cc

  Line 482 in da23fd5

  string MakeCanonical(const char* path) {

Any other information, logs, or outputs that you want to share?

• The problem is not reproducible if I switch to drive mounted at C: (SSD) instead of R: (RAM FS)

I met this issue too. But I run bazel on Windows Server 2016.
