The compiler team's explanation

Note: this error code is no longer emitted by the compiler.

This error code was replaced by E0539.

align representation hint was incorrectly declared.

Erroneous code examples:

#[repr(align=8)] // error!
struct Align8(i8);

#[repr(align="8")] // error!
struct Align8(i8);

This is a syntax error at the level of attribute declarations. The proper syntax for align representation hint is the following:

#[repr(align(8))] // ok!
struct Align8(i8);
