--- Comment #1 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
gcc-4.8 isn't maintained anymore. Moreover your testcase is invalid, 
because it invokes undefined behavior:

test.cpp:18:33: runtime error: load of misaligned address 0x0000004014e3 for
type 'Long64_t', which requires 8 byte alignment
0x0000004014e3: note: pointer points here
