Started with http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=183637 , but I'm
afraid I need to give up on this, I really have no idea whether it is correct
that the local_specializations is expected to be used and contain the
specializations from it even after tsubst_pack_expansion returns (but strangely
only when the saved local_specializations was NULL), or not. And thus whether
the bug is somewhere else, or whether the freeing of local_specializations for
packs should be postponed to some later spot (which one)?
