The c++ abi has changed, as far as I know. Debian is currently completing a
major recompile of many of its packages to match up with the new c++ abi.
AFAIR, the major improvement is that the code parser is now hand-written, more
optimised, and more capable of optimising. Also, it's capable of doing
things that were previously limited, but are required by the latest language
standards. The actual generated binary code should be smaller and more
efficient too. All in all, well worth any teething troubles to implement,
I'd say :)
