        Description

        This test fails on OSes with default 64K pages. This happens on ppc linux distributions.
        The test passes -Xss320k to the VM.

        The VM aborts with:

        oJ/8077838-ppc-hs-comp> output-jdk9-fastdebug/images/jdk/bin/java -Xss320K
        The stack size specified is too small, Specify at least 328k
        Error: Could not create the Java Virtual Machine.
        Error: A fatal exception has occurred. Program will exit.

        That's just because of the stack size computation in os_linux.cpp.
        It uses Linux::page_size, which is 64K, and Linux::vm_default_page_size(), which is 8K.
        Red/Yellow/Shadow pages are all set to 1.

        Fix: increase to -Xss328K.
