I'm unsure if it's related, but with this change to mdb.c, the following test program (which resembles Firefox's usage) asserts in mdb_cursor_init because rc is MDB_NOTFOUND.

Erm, here's the program without the errant characters:

#include <stdio.h> #include <stdlib.h> #include "lmdb.h"

#define E(expr) CHECK((rc = (expr)) == MDB_SUCCESS, #expr) #define CHECK(test, msg) ((test) ? (void)0 : ((void)fprintf(stderr, \     "%s:%d: %s: %s\n", __FILE__, __LINE__, msg, mdb_strerror(rc)), abort()))

int main(int argc,char * argv[]) {     int rc;     MDB_env *env;     MDB_dbi dbi;     MDB_val key, data;     MDB_txn *txn;     char sval[] = "foo";     char dval[] = "bar";

E(mdb_env_create(&env));     E(mdb_env_set_maxdbs(env, 2));     E(mdb_env_open(env, "./mytestdb", 0, 0664));

E(mdb_txn_begin(env, NULL, 0, &txn));     E(mdb_dbi_open(txn, "subdb", MDB_CREATE, &dbi));     E(mdb_txn_commit(txn));

key.mv_size = 3;     key.mv_data = sval;     data.mv_size = 3;     data.mv_data = dval;

E(mdb_txn_begin(env, NULL, 0, &txn));     E(mdb_put(txn, dbi, &key, &data, 0));     E(mdb_txn_commit(txn));

mdb_dbi_close(env, dbi);     mdb_env_close(env);

return 0; }
