UBSAN errors on duplicated data

[Rich FitzJohn]

Minimal R to trigger the issue:

env <- thor::mdb_env(tempfile(), dupsort = TRUE)
txn <- env$begin(write = TRUE)
txn$put("a", "A")
txn$put("a", "B")

of course setting the environment up is harder...

will be nice to see if a standalone c program has the same problem
