<h2><a name="4">Verbose <code>terminate</code></a></h2>
<p>If you are having difficulty with uncaught exceptions and want a
little bit of help debugging the causes of the core dumps, you can
make use of a GNU extension in GCC 3.1 and later:
<pre>
#include &lt;exception&gt;
int main()
{
std::set_terminate (__gnu_cxx::verbose_terminate_handler);
...
throw <em>anything</em>;
}</pre>
</p>
<p>The <code> verbose_terminate_handler </code> function obtains the name
of the current exception, attempts to demangle it, and prints it to
stderr. If the exception is derived from <code> std::exception </code>
then the output from <code>what()</code> will be included.
</p>
<p>Any replacement termination function is required to kill the program
without returning; this one calls abort.
</p>
<p>For example:
<pre>
#include &lt;exception&gt;
#include &lt;stdexcept&gt;
struct BLARGH : std::runtime_error
{
BLARGH (const string&amp; whatarg)
: std::runtime_error(whatarg) { }
};
int main (int argc)
{
std::set_terminate (__gnu_cxx::verbose_terminate_handler);
if (argc &gt; 5)
throw BLARGH(&quot;argc is greater than 5!&quot;);
else
throw argc;
}</pre>
</p>
<p>In GCC 3.1 and later, this gives
<pre>
% ./a.out
terminate called after throwing a `int'
Aborted
% ./a.out f f f f f f f f f f f
terminate called after throwing a `BLARGH'
what(): argc is greater than 5!
Aborted
%</pre>
The 'Aborted' line comes from the call to abort(), of course.
