I am blind. Can't find my error :(

Question

I am trying to setup a server that can save some messages sent from a client. I took apart some code given in an example i found here.

This is where I am now.

Ive tried to change some stuff here and there and I find the errors to be quite strange. Sometimes i comment out a function that i do not even call and then it run. Feels random when it works. I suspect there is some overflow somewhere but i can't figure out where.

I can't find anything with gdb.
