I'm running into a problem when SSA_NAME nodes that are actually in use
are being freed. I traced this down to some improper uses of TYPE_SIZE
in the tree optimizers.
The ones that *are* causing problems are in
tree-data-ref.c:estimate_niter_from_size_of_data.
A patch for this was already submitted but not approved/committed:
<http://gcc.gnu.org/ml/gcc-patches/2004-10/msg01592.html>.
And this is PR 18005.
Next time look through bug reports and patches.
Thanks,
