I'm using CGAL 4.8, not 4.9 yet. Can this be the issue?

No.

Also, I checked your command on my environment and it returned empty:
# nm -D /usr/lib/x86_64-linux-gnu/libc++.so.1|grep
_ZNSt3__113basic_istreamIcNS_11char_traitsIcEEErsEPFRS3_S4_E

From your previous email, it sounded like you had a libc++ in /usr/lib. Apparently you have a second one in /usr/lib/x86_64-linux-gnu. You may also have 2 versions of the headers. I suspect that you are using the headers from one version and the library from the other one, although I thought the interface of libc++ was quite stable.

I compiled the libc++ from here:
http://libcxx.llvm.org/docs/BuildingLibcxx.html, but used tag RELEASE_380
instead of trunk.
Where's your libc++ from? Different version/form?

Mine is the package in Debian (testing).
