--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
I can confirm that it fail starting with r218818.

Add -malign-data={abi|compat|cachineline}

Add -malign-data={abi|compat,cachineline} to control how GCC aligns
variables.  "compat" uses increased alignment value compatible with
GCC 4.8 and earlier, "abi" uses alignment value as specified by the
psABI, and "cacheline" uses increased alignment value to match the
cache line size.  "compat" is the default.
