Thanks a bunch! That made it!

Now, I've made a copy of ~/.bitcoin/chainstate dir, and move it to the path where i've compiled your program (~/development/chainstate):

$ cp -rp ~/.bitcoin/chainstate ~/development/chainstate/state

But now I'm getting:

user@localhost:~/Deveopment/chainstate $ ./chainstate
chainstate: chainstate.cc:45: int main(): Assertion `idx[0] == 'C'' failed.

Which is weird because if I add the following line before and comment the assertion like this:

~  45         cout << "DBG: "<+  46         //assert(idx[0] == 'C');


Then I get lines like:

user@localhost:~/Deveopment/chainstate $ ./chainstate
