You're probably hitting the same issues like me on openSUSE.

See Timo's response to that:

The attached patch probably helps?

Assuming I've applied the patch correctly it does not help on ppc64 and
S/390:

Well, that's annoying. I thought it would have worked. I wonder if it's still some issue with the #if not being right. Can you try once more with disabling the #if lines, i.e. just:

+static void

+copy_to_buf_last_used(struct mail_cache *cache, buffer_t *dest, bool add_new)

+ size_t offset = offsetof(struct mail_cache_field, last_used);

+//#if defined(WORDS_BIGENDIAN) && TIME_T_BITS > 32

+ offset += sizeof(uint32_t);

+//#endif

+ copy_to_buf(cache, dest, add_new, offset, sizeof(uint32_t));
