--- Comment #5 from Yvan Roux <yroux at gcc dot gnu.org> --- The latent bug on trunk is now fixed, but the issue is still present in 4.9.2 branch as the patch needs validation on that branch. I don't plan to validate it right now, as I don't always have access to the Cubox I validate trunk patch on and it's really long to do it.
