Description

The IPA rewrite for inlining small functions currently leads to invalid hops in case of special cases of no returns and remaining transient writes from previous sequence of statement blocks that are combined into a single block.

foo = function (String msg) {
    verbose = FALSE
    if (verbose)
        print(msg)
}

foo("This is an test error message.")
