test case
When you dlopen the lib that depends on libstdc++/libsupc++
and use RTLD_GLOBAL, libc++abi will crash.
I already filled the mesa bug to stop using RTLD_GLOBAL for that:
<a href="https://bugs.freedesktop.org/show_bug.cgi?id=108669">https://bugs.freedesktop.org/show_bug.cgi?id=108669</a>
But I think libc++abi should be binary compatible with
libsupc++, so I suppose there should be no crash even in that case.
Attached is a test-case.
Run "make" then "./main".
Will crash.</pre>
