In the mdb_env_cwalk() function the mc_flags member of the "mc"=20 MDB_cursor instance is not initialized.

But in the mdb_page_search_root() called a bit later (line 8407) this=20 flag will be updated from this uninitialized value.

The mc_flags member needs to be initialized to a known value.

The mc_flags member is never referenced again, so this is irrelevant.

It is referenced here:

https://gitorious.org/mdb/mdb/source/61dd017808f66ada27e89c58bc9567d5b2ad= e884:libraries/liblmdb/mdb.c#L5057

This function(mdb_page_search_root()) is called from mdb_env_cwalk()=20 with a reference to mc. and mc_flages is not initialized.
