Just ran into this.

Example:

#[typic::repr(transparent)]
struct Example;
Errors ```shell error[E0275]: overflow evaluating the requirement `::HighLevel` --> src/lib.rs:76:1 | 76 | #[typic::repr(transparent)] | ^^^^^^^^^^^^^^^^^^^^^^^^^^^ | = note: this error originates in an attribute macro (in Nightly builds, run with -Z macro-backtrace for more info) error[E0275]: overflow evaluating the requirement `::ReprAlign` --> src/lib.rs:76:1 | 76 | #[typic::repr(transparent)] | ^^^^^^^^^^^^^^^^^^^^^^^^^^^ | = note: this error originates in an attribute macro (in Nightly builds, run with -Z macro-backtrace for more info) error[E0275]: overflow evaluating the requirement `::ReprPacked` --> src/lib.rs:76:1 | 76 | #[typic::repr(transparent)] | ^^^^^^^^^^^^^^^^^^^^^^^^^^^ | = note: this error originates in an attribute macro (in Nightly builds, run with -Z macro-backtrace for more info) error: aborting due to 3 previous errors ```
