The SIGBUS is due to a misaligned address at the machine code level.
On sparc64-linux -m32 I can reproduce the SIGBUS with current 4.7 and 4.6, but
not with 4.5 or 4.4. On armv5tel-linux-gnueabi the test case causes an
alignment exception (logged and fixed up by the kernel) when compiled by 4.7 or
4.6, but not when compiled by 4.5 or 4.4.
I believe this is a dupe of one of the other alignments bugs in 4.6+ affecting
at least sparc and arm.
