gdb problem

When I use codeblocks to debug my code, gdb throws a warning message:
warning: GDB: Failed to set controlling terminal: Operation not
permitted 
and I have already google a lot, but nothing what I found can be
helpful, however indeed I have found there were other IDE tools might
have the same problem like Netbeans IDE and I think maybe this is a gdb
problem. I search it on gdb FAQ, of course find nothing. So I send you
this email, and I am hopeful that you can help me with this problem.
PS: my linux version is arch linux and I use gnome terminal
