The information you've provided is not enough to understand where the problem lies, so we'll need a bit more.
Can you enable full logging in the settings -> debugger, reproduce the problem and then post the log using code tags or in some pastebin?

For some reason your gdb doesn't support the tty command

Code

[debug]> tty /dev/pts/0
[debug]Undefined command: "tty".  Try "help".

Why do you use 7.12.50.xxxx? As far as I know these are development snapshots.
Can you try to install 7.12 or 7.12.1?
These are known to work correctly with codeblocks.

I have the same problem on Ubuntu 17.04 with the same gdb version(7.12.50~).
For unknown reason, tty command is no longer provided by this gdb. But tty command is actually the alias of "set inferior-tty"
(reference:
 https://sourceware.org/gdb/onlinedocs/gdb/Input_002fOutput.html (https://sourceware.org/gdb/onlinedocs/gdb/Input_002fOutput.html)).
So my solution to this issue is to replace "tty " with "set inferior-tty " in codeblocks' sorce file: trunk/src/plugins/debuggergdb/debuggergdb.cpp:924.

This is an acknowledged bug in this version of gdb.
For some reason this ubuntu ships with a development version of gdb.
This should be fixed in later versions of gdb.

Please ask ubuntu developers to update the gdb package to a release version.
