The bug occurs in the IPA const-prop pass. The compiler incorrectly decides
that f2 always invokes f3 with a constant aggregate parameter. This is
incorrect. There are two calls to f2, and they use different values.
The bug was introduced after 2012-11-05. I suspect this patch:
2012-11-07 Martin Jambor <mjam...@suse.cz>
PR tree-optimization/53787
but I have not proven that that is the problem.
