Thanks for all the detective work!
I think the problem is this changeset:
commit 6eb7228421c01ba48a6a88a7a5b3e71cfb70d4a9

[CRYPTO] api: Set default CRYPTO_MINALIGN to unsigned long long
Thanks to David Miller for pointing out that the SLAB (or SLOB/SLUB)
cache uses the alignment of unsigned long long if the architecture
kmalloc/slab alignment macros are not defined.
This patch changes the CRYPTO_MINALIGN so that it uses the same default
value.

struct crypto_ablkcipher;
So evidently the assumption made in this change does not work on
SLOB since it only guarantees __alignof__(unsigned long).
I think the simplest fix is to revert this changeset.
Cheers,
