Thanks for getting back!

The files at https://github.com/mozkeeler/rkv-fuzz/tree/trunk/crashes are fuzzed variants of the input data seeded from the mdb input here: They're generated when running the `american fuzzy lop` fuzzer: http://lcamtuf.coredump.cx/afl/.

It appears that rust is doing link-time optimization and deleting LMDB debug functions from the resulting binary. I'm not familiar with how the rust build system works, can we get it to stop doing this?
