I believe we got our dependence on rustic in 4.0.27.

Unfortunately, I can't reproduce this

• I'm on 1.66 and updated my rustix version and I can't reproduce this.
• CI is running on all major platforms with rustix 0.35.13 and 0.36.4 in the dependency tree and building successfully.

I just tried reproducing on two other computers and the build worked fine on both of them so this must be something specific to the environment on this one computer. Thanks for checking!

For posterity: this can be fixed with a simple cargo clean
