When I tried to set up with a probe at
pid$target::main:entry with a printf inside it, I got no output.
However, I did get a main:return from
pid:target:hello::return
I do not understand why that is happening. As I said in my last post,
I do get a _start:entry at ustackdepth =1, but to main:entry at
ustackdepth =2.
