      <application>GDB</application>, the GNU Project debugger, allows you
      to see what is going on <quote>inside</quote> another program while it
      executes -- or what another program was doing at the moment it crashed.
      Note that <application>GDB</application> is most effective when tracing
      programs and libraries that were built with debugging symbols and not

<screen><userinput>./configure --prefix=/usr --with-system-readline &amp;&amp;

    <para>
      To test the results, issue: <command>make -k check</command>. There are
      many problems with the test suite. Depends on installed compilers, there
      are differences if run locally or remotely, a large number of timeouts
      (there is a variable that can be set to increase time for timeout, but
      changing it, apparently the total number of tests is not conserved),
      there are failures associated with system readline 6.x, between others.
      Unexpected failures are of the order of 2.5%.
