// rust-lang/rust#61232: We used to ICE when trying to detect a
// collision on the symbol generated for the external linkage item in
// an extern crate.
//@ build-fail
//@ aux-build:def_colliding_external.rs
// FIXME(#83838) codegen-units=1 triggers llvm asserts
//@ compile-flags: -Ccodegen-units=16
extern crate def_colliding_external as dep1;

//~? ERROR symbol `collision` is already defined
