Message 343495 - Python tracker
I'm not marking this bug as "Fixed" as the original complaint about obmalloc'd structs with a long double not being aligned is still going to be true on 32-bit platforms for 2.7 - 3.7. We've merely increased the obmalloc alignment to 16-bytes on 64-bit platforms. So the problem should only remain for 32-bit users which at this point are likely only arm (rpi and similar low end friends not using a 64-bit OS).
