--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> ---
Fails due to:

#1  0x0000000000e6602c in verify_sra_access_forest (root=0x262cc80) at
/home/marxin/Programming/gcc/gcc/tree-sra.c:2358
2358          gcc_assert (offset == access->offset);
(gdb) p offset
$1 = -386657941920
(gdb) p access->offset
$2 = 437975778912

which must be some overflow?
