          <para>This option turns off the use of Bash's memory allocation
          (<function>malloc</function>) function which is known to cause
          segmentation faults. By turning this option off, Bash will use
          the <function>malloc</function> functions from Glibc which are
          more stable.</para>

    <para>Compilation is now complete. As discussed earlier, running the test
    suite is not mandatory for the temporary tools here in this chapter. To run
    the Bash test suite anyway, issue the following command:</para>
