It turns out that just disabling early inlining is enough and does not
make the testcase fail anywhere I tried (x86_64, ia64 and i686).  So I
posted a patch disabling it in the testcase and will commit it
shortly: http://gcc.gnu.org/ml/gcc-patches/2013-01/msg01191.html

It is true that indirect inlining on ia64 produces purely
intra-procedural opportunities for type-based devirtualization which
we do not do but should.  That is a different problem though, let's
hope it will be done in 4.9.
