The error is pointing towards the type cast done within:
static void print_int_item(const char *str, const WT_ITEM *item) { if (item->size > 0) { testutil_assert(item->size == sizeof(int32_t)); printf("%s%" PRId32, str, *(int32_t *)item->data); } else printf("%s<empty>", str); }
Verify with UBSAN build again once fixed.
