--- Comment #2 from Vladimir Makarov <vmakarov at gcc dot gnu.org> ---
Thank you for reporting this, especially for reducing the test case. The bug
is not dangerous, it does not result in wrong code generation but it might
result in worse code.
I reproduced it. It seams the validity (obsoleteness) of data was not
checked first. I'll make a patch and commit it tomorrow. If I am not able to
make it on this week, I'll do it in a week.
