</p><p>A program that uses the C++ standard library correctly
will maintain the same semantics under debug mode as it had with
the normal (release) library. All functional and exception-handling
(N.B. In GCC 3.4.x and 4.0.0, due to a bug,
<code class="code">-D_GLIBXX_DEBUG_PEDANTIC</code> was also needed. The problem has
been fixed in GCC 4.0.1 and later versions.) </p><p>The following library components provide extra debugging

e.g. <code class="code">operator[]</code>,
they will not always be run when using the <code class="code">char</code> and
<code class="code">wchar_t</code> specialisations (<code class="code">std::string</code> and
guaranteed to work. For full debug-mode support you can use the
<code class="code">__gnu_debug::basic_string</code> debugging container directly,
which always works correctly.
