Hi,

The latest mdb.master (acf20f7) fails on files that are larger than 2G, even on 64bit systems.

I could narrow it down to:

--- a/mdb/libraries/liblmdb/mdb.c +++ b/mdb/libraries/liblmdb/mdb.c @@ -4070,7 +4070,7 @@ else w2 = wsize; wres = write(fd, ptr, w2); - rc = wres == (ssize_t)w2 ? MDB_SUCCESS : wres < 0 ? ErrCode() : EIO; + rc = wres > 0 ? MDB_SUCCESS : ErrCode(); if (rc) break; wsize -= wres; ptr += wres;

After this change the environment was copied correctly.
