DEBUG: cluster: Client initialized in direct mode. Segmentation fault (core dumped)

I switched from mongodb c++ driver (which worked fine) to mongodb c driver. This is the problem

DEBUG:      cluster: Client initialized in direct mode.
Segmentation fault (core dumped)


I have written the following code to read an entry

Enter code here...

> db.persona.find()
{ "_id" : 123456, "key" : "value" }

The code is attached.

a. I am not sure I connected the driver at all. How can I check that and how can I make that happen? Where is a tool in which I can see realtime what is happening inside and around my mongodb database?
b. Is there something wrong with those code snippets? Essentially any operation that tries to read/write crashes.

Sorry you are having trouble. Taking a shot in the dark here: Did you call mongoc_init()?

http://api.mongodb.org/c/current/mongoc_init.html

If that doesn't fix it can we see the code you are running? These things are hard to diagnose without seeing the code.
