<div>Hello all,</div>
<div><br>
</div>
<div>I was wondering how llvm and clang handles the RTTI shared libraries issue mentioned here:
<a href="http://gcc.gnu.org/faq.html#dso">http://gcc.gnu.org/faq.html#dso</a></div>
<div><br>
</div>
<div>Is it using name or address comparison?</div>
<div><br>
</div>
<div>We have an architecture with several frameworks and plug-ins; some of the latter are being loaded and unloaded runtime.</div>
<div>In the past that issue caused crashes in our app, so at the moment we are overriding __dynamic_cast to detect this problem, but that's kind of messy. I'm hoping for a better solution with llvm…</div>
<div><br>
</div>
<div>(Mac OS X 10.6/10.7, clang 3.0)</div>

</div>
<div>Thanks,</div>
