I see what the problem is. cgraph_postorder doesn't help us if we're having a
cycle like here, so
nnodes = cgraph_postorder (order);
for (i = nnodes - 1; i >= 0; i--)
{
node = order[i];
if (node->analyzed && node->local.inlinable
&& (node->needed || node->reachable)
&& node->callers)
{
if (cgraph_decide_inlining_incrementally (node, true))
ggc_collect ();
}
}
after inlining into foo, which we do first, bar is no longer referenced
and is collected. We still reference it from order[0] though.
