--- Comment #2 from Martin Jambor <jamborm at gcc dot gnu.org> ---
Thinking about this more, I've come to the conclusion that on the
release branches simply disabling IPA-CP of transactional memory
clones is the best solution to this bug.  Patches for the branches
have already reached the mailing list:

https://gcc.gnu.org/ml/gcc-patches/2014-06/msg00400.html
https://gcc.gnu.org/ml/gcc-patches/2014-06/msg00401.html

However, I would very much like to avoid such simple punting on trunk
so I would appreciate if someone commented on the implications of
properly copying the tm_clone flag during cgraph_node cloning.
