rust/src/test/ui/consts/const-eval/const-eval-overflow-3b.rs

// Evaluation of constants in array-elem count goes through different
// compiler control-flow paths.
//
// This test is checking the count in an array expression.
//
// This is a variation of another such test, but in this case the
// types for the left- and right-hand sides of the addition do not
// match (as well as overflow).

// FIXME (#23926): the error output is not consistent between a
// self-hosted and a cross-compiled setup; therefore resorting to
// error-pattern for now.

// error-pattern: mismatched types
