Pin v3.28, tiny_tracer v2.6
I don't know if this is new code of tiny_tracer or new feature of Pin v3.28.
When the environment variable _NT_SYMBOL_PATH is set, and I have long since set it, the tiny_tracer (or Pin v3.28) will path and display the function name according to the debug symbol files (.pdb/.xxx).
So the functions I define in params.txt don't match.
I was forced to delete (temporarily rename) this _NT_SYMBOL_PATH environment variable.
Previous versions of Pin and tiny_tracer do not have this problem.
Below is a screenshot of an example.

And after turn off _NT_SYMBOL_PATH, it run OK
