--- Comment #7 from Bernd Schmidt <bernds at gcc dot gnu.org> ---
So far: looks like we're creating multiple init elts with the same address and
trying to put them into the same tree. Looks like we're discarding an obstack
while we still have something pointing to it, and I suspect it's related to the
warning message.
