Assertion error: when pthread returns an error, this library crashes the entire program

Hello ! I work on [SQLPage](https://sql-page.com). Stacker was recently introduced as a transitive dependency (through [sqlparser](https://github.com/apache/datafusion-sqlparser-rs/pull/1522)). I just received a bug report from an user that involves stacker: https://github.com/sqlpage/SQLPage/issues/814 The problem seems to be in https://github.com/rust-lang/stacker/blob/04d334ca6ad8ef942fef80e173c6e34bbb905a6a/src/lib.rs#L418C30-L418C51 , where `pthread_attr_getstack` returns `2` (`ENOENT`). I am not sure how to proceed, but wanted to report the issue here. Do you have an idea what may be going on and how to fix it ?
