Compiled with gcc -std=gnu99. Breaks mdv.master and mdb.RE: .... 33000000 records written testing mdb_cursor_get: unexpected error -30796: MDB_CORRUPTED: Located page was wrong type In LMDB 0.9.18, the test case instead asserted: mdb.c:5647: Assertion 'mc->mc_flags & C_INITIALIZED' failed in mdb_cursor_next() That was fixed by commit b46fc3e438d8085d5e5fc7d558c0002ee1e2753c "ITS#8406 fix xcursors after cursor_del". Then it broke again at 6b1df0e4c7fadd21d1233d7157229b2d89ccaa04 "More for ITS#8406 (xcursor fixups)", giving the MDB_CORRUPTED.

And the test can be a lot smaller and faster: static long size = 50000000; static int recordCount = 600000; static int majorIdCount = 2500; static int minorIdCount = 5000;
