I noticed the problem with optimization too, and I'm trying in my
projects to not mix builds (like with and without -g flag), or doing a
complete clean before a debug session (ccache is my friend).

At this point, I don't know if it is a gdb or a QtCreator problem.
What you get if you look into gdb directly?

(gdb executable, then do these simple commands: break file.cpp:lineno,
s for step-into, n for next instruction)
