    Certification Program The Open Brand certification program
    Test Suite VSU version 5.3.12

    Specification Base Definitions Issue 6
    Linked Problem Reports #464
    Problem Summary Changing the first mapping size from 5 to 6
    pages makes the test pass
    Problem Text The test assumes that the page after the first mapping will be unused
    when the third mapping is done, but our C library used it in malloc(),
    and this resulted in an infinite SIGSEGV loop. Changing the first
    mapping size from 5 to 6 pages makes the test pass.
