Created attachment 23513
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23513
attached almost reduced testcase.

An undefined reference to a transaction clone appears at link time.

$ g++ -save-temps -O0 -c -Wall -fgnu-tm testcase.i

testcase.o:(.tm_clone_table+0x8): undefined reference to `transaction clone for
std::_List_iterator<Game::BuildProject>::_List_iterator(std::_List_node_base*)'

The testcase is not completely reduced... I will post it a better one soon.

Considered it as high priority since it happens in the Velox stack. Thanks :)

Patrick.
