[Interest] Breakpoints stopped working with latest version on Linux

[Jason Dolan]

I've seen the GDB warning before myself but it did not seem to effect 
debugging.  According to stackoverflow ( 
http://stackoverflow.com/questions/3869380/warning-gdb-failed-to-set-controlling-terminal-invalid-argument) 
it is possibly a gdb/qtcreator bug.

The most obvious reason for your breakpoints not working is if you tried 
to debug while in Release mode (I've made that mistake before).  My 
guess is doing a fresh build put you back in debug mode.
