Issue ID: 9539 Summary: ERROR_USER_MAPPED_FILE from mdb_env_set_mapsize(env, 0) Product: LMDB Version: 0.9.28 Hardware: x86_64 OS: Windows Status: UNCONFIRMED Severity: normal Priority: --- Component: liblmdb Assignee: bugs@openldap.org Reporter: igfoo@github.com Target Milestone: ---
On Windows, with the attached program and the commands below, I am getting ERROR_USER_MAPPED_FILE from mdb_env_set_mapsize(env, 0) on the latest 0.9.28 release. The program works as expected on mdb.master.
git clone https://github.com/LMDB/lmdb.git cd lmdb git reset --hard LMDB_0.9.28 cd ..

--- Comment #4 from igfoo@github.com --- Ah, sorry, I didn't realise that 0.9.29 had been released.
Yes, with the same reproduction instructions (except using the LMDB_0.9.29 tag, commit 8ad7be2510414b9506ec9f9e24f24d04d9b04a1a) I get similar results:
