Tested OK Solaris sparcv9; Fedora 20 x86_64.
On an aside...I am still seeing some lmdb issues, even at the most basic levels. "mtest" is the only thing that's simple enough to run. "mtest2" for example:
(dbx) debug ./mtest2 (dbx) rm testdb/* (dbx) run mdb_env_open2:3825 new mdbenv mdb_env_init_meta:3472 writing new meta page mdb_env_open2:3876 opened database version 1, pagesize 8192 mdb_env_open2:3877 using meta page 0 mdb_env_open2:3878 depth: 0 mdb_env_open2:3879 entries: 0 mdb_env_open2:3880 branch pages: 0 mdb_env_open2:3881 leaf pages: 0 mdb_env_open2:3882 overflow pages: 0 mdb_env_open2:3883 root: 18446744073709551615 mdb_env_open:4484 opened dbenv 1001eac88 mdb_txn_begin:2698 begin txn 1w 1004f6f98 on mdbenv 1001eac88, root page 18446744073709551615 mdb_page_search:5068 tree is empty mdb_cursor_put:5976 ==> put db 1 key [696431], size 3, data size 48 mdb_cursor_put:6036 allocating new root leaf page mdb_page_new:6542 allocated new mpage 2, page size 8192 mdb_cursor_push:4845 pushing page 2 on db 1 cursor ffffffff7ffff5c8 mdb_cursor_put:6058 inserting key at index 0 mdb_node_add:6644 add to leaf page 2 index 0, data size 48 key size 3 [696431] Adding 334 values mdb_cursor_put:5976 ==> put db 2 key [31623120], size 4, data size 32 mdb_page_get:4907 page 8589934594 not found mtest2.c:64: mdb_put(txn, dbi, &key, &data, MDB_NOOVERWRITE): MDB_PAGE_NOTFOUND: Requested page not found t@1 (l@1) signal ABRT (Abort) in __lwp_kill at 0xffffffff6b9a900c 0xffffffff6b9a900c: __lwp_kill+0x0008: bcc,a,pt %icc,__lwp_kill+0x18 ! 0xffffffff6b9a901c Current function is main 64 if (RES(MDB_KEYEXIST, mdb_put(txn, dbi, &key, &data, MDB_NOOVERWRITE)))
In the back-mdb environment, test000 displays similar behavior.
