   > When an enclave crate is configured to compile with Xargo, instead of manually importing the `sgx_tstd` standard library, you randomly get the following error from some dependencies:
   > 
   > ```
   > error[E0658]: use of unstable library feature 'rustc_private': this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via `Cargo.toml` instead?
   > ```
   > 
   > A lot of crates compile with no issue at all, correctly linking to the tstd, but random expressions used in some crates trigger this error.
   > 
   > This is probably due to some miss-configuration of the tstd.
   > Which version of rust's std is the tstd based on? Are updates from stable Rust pulled into the tstd?
   
   Which crate will trigger this error? Can you provide a specific crate name？
