Version

9.16.1

Steps to Reproduce

Build command:

fastforge release --name=dev --jobs=release-dev-linux-deb

After upgrading sentry_flutter from 9.16.0 to 9.16.1, Linux builds started failing during the sentry-native fetch/extract phase.

Reverting back to 9.16.0 immediately fixes the problem.

This happens reliably when building a Flutter Linux app using Fastforge on a project located on a mounted Windows filesystem (/mnt/d/...) under WSL.

Expected Result

Build should succeed the same way it does on 9.16.0

Actual Result

CMake Error at sentry-native-subbuild/sentry-native-populate-prefix/src/sentry-native-populate-stamp/extract-sentry-native-populate.cmake:51 (file):
  file RENAME failed to rename

    /mnt/d/project/build/linux/x64/release/_deps/ex-sentry-native-populate1234
