error: could not compile `polars-lazy` (lib) due to previous error

Issue description

trying to compiling a small program with lazy features. Compile error.

Expected behavior

successful compilation of polars-lazy lib...

Installed versions

Before the 0.38.2 release, polars 0.38.0 worked great but now every version of polars > 0.37.0 fails due to this.
