That makes sense. Inlined functions only _appear_ to be functions.
Inlining means that the function call is replaced with the function code
by the compiler. So there simply is no function call, or return address
on the stack or whatever gdb might need to build a call stack.

Go for the compiler. Prevent it from inlining functions and gdb will
show them in the call stack. I am not sure with gcc, but it could be as
simple as turning off the optimizer.

Don't know. Why would you do that ?
