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));
+}

If that doesn't work either, I'd somehow need to get access to a big-endian CPU to try to figure out where it's going wrong.
