//! [`std::primitive::i32::MAX`]

Meta

Backtrace is from a local build of a055c5a but this also reproduces on at least rustdoc 1.48.0-nightly (dbb73f8f7 2020-09-12).

Error output

thread 'rustc' panicked at 'internal error: entered unreachable code: primitives are covered above and other `Res` variants aren't possible at module scope: PrimTy(Int(I32))', src\librustdoc\passes\collect_intra_doc_links.rs:1617:34
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md
