// 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).
