Thanks for the report. The crash has been fixed in git, but your test runs
into another (known) issue in MDB.
You're working with a very large entry, which libmdb stores in overflow pages.
In the current version of libmdb, freespace management for overflow pages is
not fully implemented, so every time you update the entry libmdb will always
use new pages (instead of reusing old pages). Thus, after a few hundred
operations, your 1GB map will be exhausted.
It looks like you won't be able to use back-mdb until this feature is fully
implemented in libmdb.
The overflow page freespace management issue is being addressed in ITS#7455. A
patch is currently being tested.
