Give us some info like what it is you put in etc...
If it produces a core file a backtrace of whats in the core would also be of use.
If you know how to use valgrind that also might catch possible issues causing this issue.
And you said that "Posting one line into a buffer that is at 90 lines( Only tested it with biographies) it will send "Buffer Full" and knock you out."
So that means that if you tried to do a 91 line it would do that?
But if you tried to do a 92 line bio it would crash?
Just trying to get a little more info on this deal lol.
