LLDB C++ API function tracer
Scroll to the bottom for the code (tracer.mm)
When I run the tracer, the return value (the value of rax after stepping out of the thread) is always zero.
I'm breaking on malloc, so the output should be some pointery looking value. I tried with other functions as well,
and I get the same issue. I also tried checking for the process state, and that says it's invalid.
