It's the ABI of:
llvm-g++ → LLVM → LLVM C backend → gcc
or:
Clang (C++) → LLVM → LLVM C backend → gcc
which is incompatible with the ABI of plain g++.

AFAICT, the native LLVM backends don't have that problem. The real problem 
with C++ is that Clang's C++ support is experimental and incomplete, so 
you're stuck with llvm-g++.

But this is about C++.
