That's why the compiler/programmer has to ask for it explicitely.
As far as I understand C++, having e.g. different vtables in a program would
make it non-conforming. Although the exact content of inline
functions/methods in .gnu.linkonce.t.* sections can change, it needs to be
compiled from the same sequence of tokens, so it should do the same thing.
Languages which don't have such requirements and where this would cause
troubles will just have to avoid using .gnu.linkonce.* sections with
SHF_MERGE flag set.
