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.
