commit 36103ba2f5db530bff24896dfc9076955fba3b5f
Author: Paul Pluzhnikov <ppluzhnikov@google.com>
Date:   Sun Mar 8 21:37:31 2015 -0700

    Refactor wordexp-test.c such that words always ends at the edge of
    unreadable page.

    This makes it easy to catch overflows, such as BZ #18043 (and BZ #18042).
