<li>The C++ front-end inherits all problems afflicting the <a href="#c-fe">C
front-end</a>.</li>
</ul>
<p><b>IA64 note</b>: The C++ front-end does not use <a
href="http://llvm.cs.uiuc.edu/PR406">IA64 ABI compliant layout of vtables</a>.
In particular, it just stores function pointers instead of function
descriptors in the vtable. This bug prevents mixing C++ code compiled with
LLVM with C++ objects compiled by other C++ compilers.</p>
