Hi Sasha,
I don't think GCC 4.6 is the minimum supported for 4.14
As far as I can see, commit cafa0010cd51f ("Raise the minimum required gcc version to 4.6") has not been applied to 4.14 and I can't see any reason such a commit should apply on a stable branch.

GCC 4.6 is the minimum supported now.
