Mongod crash on find

I've been having some problems with a query on mongodb and I managed to narrow it down to what seems to be the issue:

I figured that if the routes nested obj size is over 1695, mongod will crash on me with on that find query

[1] 32887 illegal hardware instruction mongod -vvv

Has anyone stumbled on anything like this before? Or am I doing something terribly wrong?

I do reproduce your error in 2.6.4, but not in 2.6.6. Try upgrading and see if the issue remains.
