--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- If there's currently no part in the FE that tries to release memory of this kind then a valid strathegy would be to change the current heap allocations via X[C]NEW to allocations from a frontend specific obstack and simply release the whole obstack at the point the FE transfers control to the middle-end (assuming later langhook calls from it will not reach into the data, of course). Guess FE people will have an idea of the lifetime of objects.
