        <listitem>
          <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>

        <listitem>
          <para>This parameter bypasses the search for mktime in configure
          and uses the version in glibc. The is necessary due to a change in
          gcc that has not been incorporated into this package yet.</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>
