      <application>GDB</application>, the GNU Project debugger, allows you

      Note that <application>GDB</application> is most effective when tracing
      programs and libraries that were built with debugging symbols and not

    <para>
      To test the results, issue: <command>make -k check</command>. There are
      many problems with the test suite. Depends on installed compilers,
      differences if run locally or remotely, many 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) and also depends
      on some environment variables being set.
      Failures are of the order of 1000.
