mdb_dump didn't complain.

When looking at the code for mdb_env_copyfd1 (the copy with compaction
function), there is this clause[0]:
if (rc == MDB_SUCCESS && root != new_root) { rc = MDB_INCOMPATIBLE; /* page leak or corrupt DB */ }
Since this happens at the end of the function, and I'm seeing the
mdb_copy -c takes a while, I figured this was the error that I was seeing.
If this isn't it, then what am I looking at? If it is a corrupt DB, is
there anything I can do to figure out how to fix this?
Try using mdb_dump to get a backup instead, see if it succeeds or complains.
